Welcome to the seventh episode of reading to coffee.
Today topic is: SPACE
1. Neutron stars can spin more than 600 times per second.
2. A teaspoon of neutron star material would weigh about 10 million tons. A neutron star has a mass of about 1.4 times the mass of the sun, but is not much bigger than a small city, about 15 km in radius.
3. Space is completely silent, sound does not spread in vacuum.
4. One million Earths could fit inside the sun – and the sun is considered an average-size star.
5. 1 light year = 9 460 730 472 580 044 meter
6. Pluto is smaller than USA.
7. We know more about Mars and our Moon than we do about our oceans. We have fully mapped 100% of the surface of Mars and Earth’s Moon, whereas we have only been able to map roughly 5% of the ocean floor.
8. Our moon is moving away from Earth at a rate of 4 cm per year!
9. Space is full of trash like used rockets parts and satelites. It is dangerous for ISS because even small trash long a few cm could do a fatal destroy.
10. The sun makes up 99,8% of Solar system mass.
11. All planets of Solar system could fit between the Earth and the Moon.
12. A day on Venus is longer than a year there.
13. It take 12 years when satellite travel to Neptune.
14. Check this nice video of size comparison.
15. Clap your hands once, after a second clap again. The two claps were actually done about 30,000 km apart thanks to the Earth motion in space.
