A planet is any of the large bodies that revolve around the sun in the solar system or a similar body associated with another star.

An asteroid is an object in space that's smaller than a planet. A meteor is an asteroid or other object that burns and vaporizes upon entry into the Earth's atmosphere.

If a meteor plunges through the atmosphere and lands on the surface of the earth, it's known as a meteorite. Meteoroids are small particles of comets or asteroids that are in orbit around the sun.

We often refer to a meteoroid as a small asteroid. Meteor exploded in the atmosphere resulting into a fireball is known as a bolide.

An uncle is a person’s parent's brother, parent's brother-in-law, parent's cousin, or some times parent’s male friends if you wish to get something from them?

If you cry for mercy, say uncle.
