Fascinating Astronomy Facts
1. Our Sun is one of over 100 billion stars in the Milky Way galaxy, and the Milky Way is one of over 100 million galaxies in the universe.
2. The planet Saturn would float on water—it’s the only planet in our solar system that would.

3. The black hole in the center of the Milky Way galaxy is millions of times the mass of the Sun.
4. The planet with the hottest surface temperature is not Mercury, but Venus, because of the Greenhouse Effect of its atmosphere.
5. Earth is the only known planet with plate tectonics.
6. The Sun’s core releases energy equivalent to 100 billion nuclear bombs per second, and that energy travels thousands of years through its layers before it is emitted as heat and light to power the solar system.

12. Neutron stars, which are leftover from the deaths of massive stars in supernova explosions, are so dense that just a bowlful of neutron star material has more mass than the Moon.
13. Neutron stars also spin up to 500 times per second and are some of the fastest-spinning objects known to astronomers.
