Solution:

A shooting star is a meteorite that catches fire while entering the earths atmosphere: Explanation:A shooting star is nothing but meteors burning up when they enter the earth's atmosphere.?The Shooting Star looks exactly the same as the Inverted hammer.Meteorite:A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.Heavenly matter landing on the earths surface is known as Meteorite.A meteor is simply an asteroid that attempts to land on Earth but is vaporized by the Earths atmosphere.?If chunks of a comet melt off as it passes close to the Sun, this debris can be left behind to later dazzle us, Earthlings, with a meteor shower.Additional InformationStars:Stars are a massive self-luminous celestial body of gas that shines by radiation derived from their internal energy sources. The twinkling of stars is due to the atmospheric refraction of star-light.The refraction of light caused by the earth's atmosphere having air layers of varying optical density is called atmospheric refraction.This causes the light from the star to twinkle when seen from the ground.Satellite:An object moving at a constant speed can be a satellite.A satellite is a moon, planet or machine that orbits a planet or star.A satellite moves at a constant speed around a larger object.Earth is a satellite because it moves around the sun.The moon is a satellite because it moves around Earth.Earth and the moon are called "natural" satellites.
