Here on Earth, people don’t really pay attention to what’s out there, unless they are watching Star Wars. There are plenty of cool, interesting facts about the universe that we don’t even know!
1. In space, the skin of your feet peel off!
This is a pretty gross fact but in the micro-gravity environment, astronauts are not using their feet to walk. Therefore the skin on their feet starts to soften and flakes off. As laundry facilities do not exist in space, astronauts will wear the same underwear and socks for a few days. Those socks then need to be taken off very gently. If not those dead skin cells will float around in the weightless environment
2. One million Earths can fit inside the Sun
The Sun makes up 99.8% of the entire mass of the whole Solar System. One million Earths would be needed to be the same size as the Sun.
3. You become taller in Space
This one goes out to all you shorties out there! (“YEEAA DAS ME”- Arlene) Another change to the human body in micro-gravity is that the spine straightens out, as gravity is not pushing you down. In fact you can be up to as much as 5cm taller in the Space Station.
4.We are moving through space at the rate of 530km a second
Our Galaxy – the Milky Way is spinning at a rate of 225 kilometers per second. In addition, the galaxy is travelling through space at the rate of 305 kilometers per second. This means that we are traveling at a total speed of 530 kilometers (330 miles) per second. That means that in one minute you are about 19 thousand kilometers away from where you were. Scientists do not all agree on the speed with which the Milky Way is travelling – estimates range from 130 – 1,000 km/s. It should be said that Einstein’s theory of relativity, the velocity of any object through space is not meaningful.
5.Mercury and Venus are the only two planets in our solar system that do not have any moons
Because Mercury is so close to the sun and its gravity, it wouldn’t be able to hold on to its own moon. Any moon would most likely crash into Mercury or maybe go into orbit around the sun and eventually get pulled into it. Why Venus doesn’t have a moon is a mystery for scientists to solve.
6.A light year is the distance covered by light in a single year. This is equivalent to 6 billion miles!
7. Mercury, Venus, Mars, Saturn, and Jupiter can be seen with the naked eye
Saturn is the fifth brightest object in the solar system and is also easily studied through binoculars or a small telescope. However, you can only see them in a certain time of year with the naked eye.
8.The Sun makes a full rotation once every 25-35 days.
Did you guys think the sun just sits there and doesn’t move? Of corse, not the sun needs to move too!
9.Neptune takes 165 years to make one orbit of the moon. This means that since its discovery in 1846, it has only completed just one orbit!
You think a year takes for ever? Saturn, Neptune, Uranus day’s are longer than a year. So once we have had our new years ten times the planets haven’t even orbited the sun in a year.
10. There are three main types of galaxies out in space, and they are spiral, elliptical, and irregular.
A galaxy in which the stars and gas clouds are concentrated mainly in one or more spiral arms.
An elliptical galaxy is a type of galaxy having an approximately ellipsoidal shape and a smooth, nearly featureless brightness profile. Unlike flat spiral galaxies with organization and structure, they are more three-dimensional, without much structure, and their stars are in somewhat random orbits around the center.
An irregular galaxy is a galaxy that does not have a distinct regular shape, unlike a spiral or an elliptical galaxy.
Yet, there are still another billion of awesome facts about space. I mean, this is the universe we are talking about!
