20 Fun Facts About Astronomers You Didn’t Know
The Moon is shaped like a lemon:
Our natural satellite is not even close to being round, despite how it appears in the night sky. The Moon is lemon-like, with flattened poles and bulges on its equator’s near and far sides. It is believed that its peculiar structure was developed during early encounters with Earth.
There is total silence in space:
This is the first space fact in our list of 20 fun facts about space and astronomers you probably didn’t know about. There is no atmosphere or air in space. No medium for sound waves to go to since there is a vacuum. That means that even if you shout the loudest, no one will be able to hear you in outer space! While radio waves (electromagnetic waves) can travel across space, sound waves (mechanical waves) require a medium. Astronauts use radios to maintain contact in space since radio waves can still be delivered and received in a vacuum.
A day on Mercury is twice as long as a year:
In reality, a Mercurian year is made up of 88 Mercurian days, while an Earth day is 59. The period from dawn to sunrise, known as a “solar day,” is equal to 176 Earth days, which is twice as long as a Mercurian year, due to Mercury’s extraordinarily eccentric orbit and alignment with the Sun.
The solar system’s hottest planet has a surface temperature of 450° C:
Venus is the solar system’s hottest planet. The average surface temperature of this searing planet is roughly 232 °F (450 °C). Mercury, not Venus, is the planet nearest to the Sun. Mercury experiences relatively high-temperature fluctuations because it lacks an atmosphere to control its climate. On the other hand, Venus has the planet with the densest atmosphere. Venus gets tremendously hot because its atmosphere retains heat.
Mars might have life
Mars is the planet in our solar system with the highest likelihood of supporting life (apart from Earth). In a rock sent back from Mars in 1986, NASA discovered what they believed to be the remains of small living organisms. We will never be able to see some stars. Since the Big Bang, most space objects have revolved away from one another. In actuality, the Universe’s expansion is quickening.
The first population of stars to form in the Universe are now too far away for humans to ever hope to detect them, as sections of space are zooming away from one another at an ever-increasing rate, even with the most advanced telescopes of the future. Still, there is some hope since we may indirectly detect them by looking for the powerful radiation bursts they release after their life.
Some stars are too far away for us to see:
Since the Big Bang, most space objects have revolved away from one another. In actuality, the Universe’s expansion is quickening. The initial population of stars to form in the Universe is now too far away for us ever to hope to observe them, even utilizing the best present or future telescope, as sections of space are zooming away from one another at an ever-increasing rate. Still, there is some hope since we may indirectly detect them by looking for the powerful radiation bursts they release after their life.
The number of stars in space is unknown:
It is impossible to precisely estimate how many stars exist because of the immensity of space. Currently, astronomers and scientists can only estimate the number of stars in our galaxy, the Milky Way. Since there are between 200 and 400 billion stars in the Universe and billions of galaxies, the number of stars is truly priceless.
The hypothetical opposites of black holes are called white holes:
The gravitational pull of black holes is so great that even light cannot escape from them, giving them their reputation as voracious eaters. White holes, on the other hand, are their theoretical opposite. Instead of trapping light and matter like their dark relatives, they spew it out. Astronomers are thinking about how they may form in the real world, but they are now merely speculative objects.
Cost of a full NASA space suit: $12,000,000:
The backpack and control module accounted for roughly 70% of the overall expense. If converted to today’s prices, the real cost would be something in the neighborhood of $150 million. NASA has been using spacesuits since 1974 up until this point. Due to a lack of spacesuits, the first all-female spacewalk was postponed till 2019.
A blue sunset appears on Mars:
According to NASA, sunsets on Mars would appear bluish to human viewers viewing the red planet, as colours are intensified in Earth’s sunsets. While normal daylight makes the famous rusty dust colour of the Red Planet the most noticeable to the human eye, fine dust significantly increases the visibility of the blue near the Sun’s portion of the sky.
The solar system is composed of 99.86% of the MASS of the Sun:
With a mass roughly 330,000 times that of the Earth, the Sun makes up 99.86% of the mass in our solar system. Did you know that the Sun contains approximately three-quarters hydrogen and the remaining four percent helium? Would the Sun’s voice, if it had one, be high and squeaky due to all that helium?
Neutron stars have a maximum spin rate of 600:
The smallest and densest stars in the known cosmos are neutron stars, which despite having a radius of only around 10 km (6 mi), may very well have just a few times the mass of the Sun. When they emerge from a core-collapse supernova star explosion, they can rotate up to 60 times per second, and due to their physics, they have also been observed spinning at 600–712 times per second.
The Sun sheds one billion kilograms every second:
As part of the solar wind, hot, energetic particles from the Sun’s upper atmosphere shoot out into space. Every second, our star sheds about 1.3 trillion trillion trillion particles. This is equivalent to about one Earth every 185 million years or one billion kilos of matter per second.
The Sun can accommodate one million Earths:
If the Earth were compressed into the Sun, it could fit within by around 1.3 million, or 960,000, if it kept its spherical shape. But how many Earths can you imagine?
Perhaps there is a planet made of diamonds:

This is a rather astounding space fact. Scientists from Yale University have discovered a rocky planet called 55 Center. Its mass is eight times bigger and twice as big as Earth’s. It might have a surface consisting of diamond and graphite. Despite being 40 light years away, it may be seen with the unaided eye in the Cancer constellation.
In space, enormous volumes of water have been discovered:
An international team of scientists has found a big and ancient water reservoir whirling around a huge black hole at the center of a quasar galaxy 12 billion light-years from Earth. Researchers from the California Institute of Technology claim that the faraway water vapor is 100,000 times more massive than the Sun and at least 140 trillion times larger than all the water in the oceans on Earth. According to the researchers, the distant black hole is being fed by enough water vapor and other chemicals, such as carbon monoxide, that it may expand to six times its current enormous size.
On Venus, a day lasts more than a year:
Venus has the most circular elliptic orbit of all the planets as it revolves around the Sun. Only 1.5 million Kilometres separate its aphelion and perihelion, meaning its orbital phase is only 0.007. The mass of the Earth is 0.0167, for comparison. About 3° 24′ is the inclination of Venus’ orbit concerning the ecliptic plane. Venus takes 224.70096 Earth days to complete one full circle around the Sun, the same way all the other planets do. The duration of Venus’ rotation around its axis was unknown for a very long time.
The atmosphere of Venus included minute characteristics that suggested the clouds cycled for around four days, counterclockwise to Venus’ orbit. In 1962, radar broke through the clouds and measured the planet’s rotational cycle. Venus rotates once every 243.0185 Earth days, whereas the Earth rotates once every one Earth day. If seen from the north pole, the planet revolves in a clockwise direction. The west is where the Sun rises.
Despite the ISS’s lack of gravity:
The ISS may appear gravity-free in images of people aboard, but the onboard gravity is just 10–11% less than that of the Earth’s surface. Due to the ISS’s ongoing free-fall, astronauts float freely, similar to skydivers. The ISS is different in that it also moves horizontally. The horizon curls away beneath the ISS at the same rate that it moves “sideways” and falls towards Earth, keeping it in orbit and giving anybody on board the illusion of weightlessness.
The Moon was formerly a part of the Earth:
One theory says while Earth was still a young planet and collided with a large object, a chunk of the Earth was broken off, resulting in the Moon. The Earth’s gravitational attraction caused this object to start orbiting it. According to theory, the Moon was created after the Earth collided with a smaller planet around Mars’ size. There was proto-Earth and Theia before Earth and the Moon (a roughly Mars-sized planet).
The giant-impact hypothesis postulates a collision between these two bodies in Earth’s early history. Nearly all of Earth and Theia melted and reformed as one body during this violent impact, with a small portion of the new mass spinning off to produce the Moon as we know it. Scientists have experimented with impact modeling to get the closest match, adjusting Theia’s size to explore what happens at various sizes and impact angles.
Yearly, the Moon’s distance increases:
This is the last space fact in our list of 20 fun facts about space and astronomers you probably didn’t know about. The Earth is pulled toward the Moon, giving our planet a faintly egg-shaped form. Water is even more impacted by it, leading to the formation of tides and the oceans piling up toward one side of the Earth, or “tidal bulge.” The Moon drags this bulge around with it as it revolves. The bulge travels ahead of the Moon’s orbital position because Earth rotates faster than the Moon (27.3 days vs. 24 hours).
The Moon pulls back on it, thereby attempting to slow it down, and as a result, the Earth’s rotation rate steadily decreases over time. The tug of war between the two bodies results in energy loss for Earth and gain for the Moon as they interact through gravity. This increase in energy has caused the Moon to spiral outward steadily, distancing itself from us by 3.8cm annually.
