Venus has a slow axis rotation which takes 243 Earth days to complete its day. One day on Venus is longer than one year. This means the footprints of the Apollo astronauts, along with spacecraft prints, rover prints, and discarded material, will be there for millions of years. The Moon has no atmosphere, which means there is no wind to erode the surface and no water to wash the footprints away. The footprints on the Moon will be there for 100 million years. It’s 40 light-years away but visible to the naked eye in the constellation of Cancer. It may have a surface made up of graphite and diamond. It is twice the size of Earth and has a mass eight times greater. Research by Yale University scientists suggests that a rocky planet called 55 Cancri e. There may be a planet made out of diamonds.Īs space facts go, this is pretty impressive. They can rotate up to 60 times per second after they are born from a core-collapse supernova star explosion and have been known to spin as fast as 600-712 times per second because of their physics. Neutron stars are the densest and tiniest stars in the known universe and although they only have a radius of about 10 km (6 mi), they may have a mass of a few times that of the Sun. Neutron stars can spin 600 times per second. ![]() In 2019, the first all-female spacewalk was cancelled because of spacesuit availability. Up to now, NASA reuses the spacesuits that were made in 1974. If we were to convert the total amount to today’s pricing, this would be approximately around $150 million. A full NASA space suit costs $12,000,000.Ībout 70% of the total cost was for the backpack and control module. Halleys Comet won’t orbit past Earth again until 2061.ĭiscovered in 1705 by Edmond Halley, the famous comet was last seen in 1986 and is only seen once every 75 to 76 years. That number is between 200-400 billion stars and there are estimated to be billions of galaxies so the stars in space really are completely uncountable. Right now, scientists and astronomers use the number of stars only within our galaxy, the Milky Way, to estimate. The sheer size of space makes it impossible to accurately predict just how many stars we have. Nobody knows how many stars are in space. In 1986, NASA found what they thought may be fossils of microscopic living things in a rock recovered from Mars. Of all the planets in our solar system (apart from Earth), Mars is the one most likely to be hospitable to life. This atmosphere traps heat, making Venus very hot. Venus, on the other hand, has the thickest atmosphere among all planets. Mercury has no atmosphere to regulate temperature so it has a very large temperature fluctuation. Interestingly, Venus is not the closest planet to the Sun, Mercury is. ![]() This scorching planet has an average surface temperature of about 232 ☏ (450 ☌). The hottest planet in the solar system is Venus. The hottest planet in our solar system is 450° C. Astronauts use radios to stay in communication while in space since radio waves can still be sent and received in a vacuum environment. While sound waves (mechanical waves) need a medium to travel, radio waves (electromagnetic waves) can travel in the void of space. That means, no one will hear you scream in space, even if you shout the loudest! Since it is a vacuum, sound waves will have no medium to travel to. So let’s get started! 50 Incredible Space Facts 1. From the jaw dropping to the awe inspiring, the universe we live in is a magnificent bundle of chaos and majesty. Below we have put together a list of 50 of the most ‘out there’ space facts to inspire young minds, and old alike. ![]()
