Saturn’s rings are made up of salt, dust, and rock fragments.The sun seems to be 1600 times fainter from Pluto than it is from Earth.More than 4 billion years ago, our solar system formed.The longest possible solar eclipse is 7.31 minutes.Mars looks red when it is littered with rust.Because of zero gravity, astronauts are unable to cry adequately in orbit.Throughout every given moment, 41 per cent of the moon is not visible from Earth.Here are some fascinating things about space and the celestial bodies like the earth, the solar system, planets, and the moon that you might not have known. There are billions of galaxies, stars, and planets out there that we will never hear about. Human space travel is only in its early stages. Despite its immensity, space continues to grow. Interesting Facts about Space & Celestial Bodies!
The various seasons of the year are caused by this shift.Īn orbit is a direction that the Earth takes when it revolves around the Sun. The axis of rotation of the Earth is rotated by 23.5 degrees. One complete rotation of the Earth around the Sun takes a whole year (365 days). The Earth takes 24 hours to complete one rotation around the sun. The rotation of the Earth around the Sun is referred to as revolution. The Earth’s rotation is defined as its rotating on its axis. The Moon, for example, orbits around the Earth, and the Earth revolves around the Sun. It is used as one body goes around another, while rotation refers to movement around an axis. The term “revolution” is sometimes used interchangeably with “rotation.” In certain disciplines, such as astronomy and similar topics, however, revolution is referred to as an orbital revolution. 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.

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.

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
