If the axis crosses through the centre of mass of the body, the body is said to rotate or spin. A rotating axis is a line that three-dimensional objects such as the Earth, Moon, and other planets often spin along. Credits: Britannica Celestial Bodies: Difference Rotation and Revolution Credits: YouTube What is Rotation?Ī rotation is the circular movement of an object around a fixed axis. If a meteor is massive enough, it can strike the earth’s crust to form a crater. They are often referred to as shooting stars. It causes lines in the sky to appear as if a star has collapsed. Meteors are usually tiny and burn up celestial bodies in the atmosphere as they enter the Earth’s atmosphere.
There are objects from space that enter our atmosphere as a result of our planet’s gravitational force. Credits: Wikipedia Meteors and Meteorites Other galaxies are usually so far away that they appear as stars in the night sky. The sun and solar system are elements of our galaxy, known as the Milky Way. Galaxies are large groups of stars that are held together by gravity. These are mostly located between Mars and Jupiter in a region known as the asteroid belt. Credits: Forbes AsteroidsĪsteroids are celestial bodies in space that are thin, irregularly formed rocks made of metal or minerals that revolve around the sun. It revolves around it due to the magnetic force of the Earth. These are essential components of many celestial bodies. Satellites are rotating satellites that revolve around planets. Our earth, too, is a planet, and it is the only known location in our world of life. Planets could be composed of minerals, elements, and chemicals like hydrogen, nitrogen, and methane.
Planets travel in fixed orbits around the earth. They are the massive spherical structures that revolve around the sun. Because of their proximity to the sun, the ice on them vaporizes, resulting in the magnificent tail behind them. They are the tiny ice and rock pieces that come from the solar system’s outskirts. Our sun is a medium-sized star that provides us with energy that allows us to live on Earth.
Stars are massive in scale and have a strong magnetic pull. They generate energy by converting hydrogen gas into helium in their hearts. Stars are massive balls of hot gases that can generate their own light. Read: Explore Different Astronomy Careers Stars
