Celestial Bodies

Last Updated : 07 Nov, 2023

Celestial Bodies are all-natural bodies seen in the sky outside the Earth’s atmosphere. Celestial Bodies are also called Heavenly Bodies. Celestial Bodies include stars, planets, and their moons, as well as comets, asteroids, etc. The moon is the celestial body closest to Earth. Stars are celestial bodies that emit their own light. Our sun is a star as well. Celestial Bodies are things in the sky, like stars, planets, the moon, and even the sun. They’re objects that exist in space, far away from Earth. When you look up at the night sky, you see some of these celestial bodies. In this article, we are going to learn about celestial Bodies in depth.

What are Celestial Bodies?

Celestial bodies are things that exist in the vast space above us, in the night sky and beyond. They include various things like stars, planets, moons, asteroids, comets, and even our own sun. Planets are smaller celestial things that reflect light from stars rather than producing their light and energy, whereas stars are described as large celestial bodies that create light and energy through nuclear fusion.

Celestial Bodies Definition

Celestial bodies are natural objects in the universe that exist in space, outside of Earth’s atmosphere. These objects can vary in size, composition, and characteristics. The study of celestial bodies provides valuable insights into the cosmos and helps us better understand our place in the vast expanse of space.

Examples of Celestial Bodies

The Sun, The earth, The Moon, Mars, Jupiter, Saturn, Venus, Mercury, Halley’s Comet, The Milky Way, The Andromeda Galaxy, Alpha Centauri etc. these are the examples of celestial bodies.

Planets-in-our-Solar-System

Stars

Stars are celestial bodies which revolve independently within the universe around the center of the galaxy. Stars are defined as objects with a self-emitting light source that are created as a result of ongoing thermonuclear fusion. Nuclear fusion, which results from the transformation of hydrogen into helium and is thought to be the source of self-emitting light, is how the light is produced. They move only in accordance with their fixed place in the universe, but since their movements are so minute, no one can see them.

Planets

Planets are celestial bodies that are part of the universe. Planets are defined as universe objects that don’t have a self-emitting source of light and proceed along an established path. The star, or sun, which is present in the solar system, serves as the planets’ source of illumination. The solar system has eight planets. These planets range in size and temperature, with the ones closest to the sun having a warm temperature and those further from it having a cold one.

Satellites

Satellites are objects that either occur naturally or man-made that used to go around a planet that is larger than it and rotates in its axis. There are various satellites including the moon present in the solar system. Therefore, on the basis of existence satellites are divided into two main categories:

Natural Satellites: Any celestial body present in space that revolves around a planet larger than it in a fixed orbit is called the natural satellites. The solar system consists of six planetary satellite system out of which 205 satellites are known to be natural satellites.
Artificial Satellites: Any object that people have made and launched into orbit using rockets is called the artificial satellite. Presently, there are over a thousand active satellites orbiting the Earth

Comets

Comets are like cosmic “dirty snowballs.” They are made up of dust and tiny rocks mixed with frozen gases like water, carbon dioxide, methane, and ammonia. These materials come together to create a comet’s nucleus, which is the solid core of the comet. Comets are fascinating celestial objects that have been liked by people for centuries.

Asteroids

Asteroids are rocky objects that vary in size, from a few feet to hundreds of miles across. They are leftover building blocks from the early solar system when planets were forming. You can think of them as space rocks that orbit the sun.

Meteors and Meteorites

Meteors are the streaks of light you see when small space objects enter the Earth’s atmosphere and burn up, while meteorites are the pieces of space objects that survive the journey and land on Earth’s surface. Both meteors and meteorites help us understand the universe better. Meteors are often called “shooting stars.” They are the streaks of light you see in the night sky when a small object from space, like a tiny asteroid or a piece of a comet, enters Earth’s atmosphere. Meteorites can come in different shapes and sizes, and they are pieces of space rocks that have landed on Earth. Scientists study them to learn more about the materials that make up our solar system.

Galaxies

A galaxy, celestial body is a massive collection of stars, gas, dust, and dark matter that is bound together by gravity. Our home galaxy is called the Milky Way, and it contains billions of stars, including our Sun. There are many different types of galaxies, like spiral galaxies with swirling arms, round-shaped elliptical galaxies, and irregular galaxies with no specific shape. Galaxies can be very, very big, containing billions or even trillions of stars, and they can be incredibly far away from us in space.

The Sun

The Sun is a celestial body. It’s a massive, glowing ball of hot, burning gas (mainly hydrogen and helium) that serves as the center of our solar system. The Sun is a star, and it provides us with heat, light, and energy, making life on Earth possible. It’s one of the most important celestial objects in our sky and plays a central role in our solar system.
