1. No asteroids have ever been observed to hit the Sun, but that doesn't mean that they don't! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.

2. Asteroids can also help us understand the evolution of our solar system. Meteorites, which are pieces of asteroids, have allowed us to determine the age of the solar system from radioactive dating. Some asteroids are fairly pristine, and their rocks record events from the very early solar system.

3. NASA knows of no asteroid or comet currently on a collision course with Earth, so the probability of a major collision is quite small.

4. Saturn's rings are thought to be pieces of comets, asteroids or shattered moons that broke up before they reached the planet, torn apart by Saturn's powerful gravity. They are made of billions of small chunks of ice and rock coated with another material such as dust.

5. The Galactic Center (or Galactic Centre) is the rotational center of the Milky Way galaxy; it is a supermassive black hole of 4.100 ± 0.034 million solar masses, which powers the compact radio source Sagittarius A*.
