In astronomy, the terms object and body are often used interchangeably. However, an astronomical body or celestial body is a single, tightly bound, contiguous entity, while an astronomical or celestial object is a complex, less cohesively bound structure, which may consist of multiple bodies or even other objects with substructures.
Celestial bodies or heavenly bodies are objects in space such as the sun, moon, planets, and stars. They form a part of the vast universe we live in and are usually very far from us.

So what exactly are celestial bodies? Why should we even study them in the first place? Why is there a need for us to find out if we are the only ones here or not? All of these questions will be answered in this article. We will be taking a deeper look into the space that surrounds our planet Earth and we will try to understand everything in detail...
(Image will be uploaded soon) A star is a form of a celestial object made up of a shining spheroid of plasma held together by its own gravity. The nearest star to the Earth is the Sun. Several other stars are visible to the naked eye from the Earth during the night time, looking at a multitude of fixed luminous points in the sky due to their enormo...
(Image will be uploaded soon) A planet is a body that revolves around a star that is enormous enough to be spherical by its own magnitude, is not big enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals. The word planet is an ancient word that ties to history, astrology, science, mythology, and religion. Fi...
(Image will be uploaded soon) It is a natural celestial object with a recognized orbit around a planet of the Solar System, some as small as a kilometer across. In the Solar System, there are six terrestrial satellite systems covering 185 known natural satellites. Four IAU-Mentioned dwarf planets are also known to have natural satellites: Pluto, Ha...
(Image will be uploaded soon) A comet is an icy object which is present in a Solar System object that, when travelling close to the Sun, warms and starts to emit gases, a practice known as outgassing. This creates a visible atmosphere or coma, and sometimes also a tail. These occurrences are due to the effects of solar radiation and the solar wind ...
(Image will be uploaded soon) Asteroids are small planets, especially of the inside Solar System. Big asteroids are also called planetoids. These expressions have historically been applied to any astronomical body orbiting the Sun that did not look like a planet-like disc and was not seen to have characteristics of a lively comet such as a tail. As...

(Image will be uploaded soon) A galaxy is a gravitational system of stars, interstellar gas, stellar fragments, dust, and dark matter. The word galaxy is originated from the Greek word galaxies (γαλαξίας), literally meaning "milky", a reference to the Milky Way. Galaxies are in size from small with just a few hundred million (\[10^{8}\]) stars to c...
We hope that the article was helpful for you to understand what celestial bodies are and why exactly they are important. The space around us is very interesting and it takes a good amount of curiosity to figure out what are the basic differences between these objects and what makes them so unique.
There are four main categories of classifications when determining the type of celestial body an object is. These classifications are: terrestrial planets (Mercury, Venus, Earth, and Mars), gas giants (Jupiter and Saturn), ice giants (Uranus and Neptune), and dwarf planets (Pluto, Eris, Haumea, and Makemake). Ceres at this current time is still ...
Nov 3, 2023 · Any natural body outside of the earth’s atmosphere is called a celestial body. Celestial bodies are classified into seven types such as stars, planets, comets, etc.
Celestial bodies, also known as heavenly bodies, are objects that inhabit the universe – such as the sun, the moon, the planets, and the multitude of stars. They are part of the vast universe we live in. The night sky, with its myriad twinkling points, is adorned with these objects. When viewed through a telescope, they look mesmerizing.

The four outer planets Jupiter, Saturn, Uranus, and Neptune, are gas giants - largely hydrogen and some helium, with small solid cores. They're also called Jovian planets. In 1930, an object was discovered orbiting the Sun beyond Neptune; it was named Pluto.
