1.In space the skin on your feet peels off!
Due to zero gravity in space the skin of feet removes as a thin layer.
2. One million Earths can fit inside the Sun.
Compared to Earth, the Sun is enormous! It contains 99.86% of all of the mass of the entire Solar System. The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth. It is so large that about 1,300,000 planet Earths can fit inside of it. Earth is about the size of an average sunspot!

3.You become taller in Space.
Astronauts in space can grow up to 3 percent taller during the time spent living in microgravity, NASA scientists say. That means that a 6-foot-tall (1.8 meters) person could gain as many as 2 inches (5 centimeters) while in orbit.

4.The hottest planet is not the closest planet to the Sun.
We know that the radiation intensity is too much towards the body that radiates em radiation. The Sun is the ultimate source of our solar system and mercury is the closest planet to the Sun. But interestingly it is not hottest planet at all of our solar system. The hottest planet is venus which is the next closest planet to the Sun. This is due to the existence of huge percentage of greenhouse gas carbon-dioxide and sulfur-dioxide.
A surface probe would not exist on the surface of Venus for very long. This is an reconstruction of the surface of Venus as captured by Radar by the space craft Magellan in the 1990s. (image credit: E. De Jong et al. (JPL), MIPL, Magellan Team, NASA)
5.The moon looks bigger on the horizon
The moon looks bigger on the horizon due to various possible explanation. As example Refraction and distance, Apparent distance hypothesis, Relative size hypothesis, Angle of regard hypothesis, Ebbinghaus illusion.
6. You can cry in space but your tears don’t fall
Due to microgravity in the space there are no falling out of any substance. So tears drop also do not fall.
Astronauts can, certainly, tear up -- they're human, after all. But in zero gravity, the tears themselves can't flow downward in the way they do on Earth. The moisture generated has nowhere to go. Tears, Feustel put it, "don't fall off of your eye ... they kind of stay there” NASA spacewalk officer Allison Bollinger, who oversaw Feustel's EVA, confirmed this assessment. "

7. There is a dwarf planet named after an Easter island legend
Makemake is this planet which was first observed in March 2005 and it's Officially known as 2005 FY9, the tiny planetoid was nicknamed Easterbunny by the group.

8.The Apollo crews did not have any life insurance.
In general maximum people are interested in life insurance for as much as tiny incident. But 99% risky fact is the lunner space landing in Apollo space mission and the crew involved in this mission have no life insurance.

9.In space metal sticks together
In a vacuum like space, when two pieces of metal touch each other they bond together. This is a process called cold welding. On the Earth because of the oxygen in our environment this does not happen naturally but it is used during some manufacturing processes. It is something to take into account but it is not usually a problem as the astronaut’s tools maintain an oxide layer even when leaving Earth.

10.Dirty underwear and toilet paper has helped grown plants on the ISS
According to NASA "This toilet paper is not like what you normally think of as toilet paper "It consisted of two layers of coarsely woven gauze, 4 by 6 inches in dimension sewn together at the edges with a layer of brown tissue sandwiched in-between. It works very well for its intended purpose. It also makes a wonderful sprouter." After Pettit solved a problem that was causing the seeds to stay too cold to germinate, the seeds sprouted in the underwear-toilet paper planter within 2 days.”
