Difference Between Stars and Planets - A Complete Guide

It's a good idea to think about what these bright dots are.

What Do These Dots Stand For?

The dots are, of course, Stars and Planets.

Star

A celestial body with its own light and energy is known as a star.

A star is a massive, gleaming ball of heated gas made primarily of Hydrogen and Helium.

Stars are massive, brilliant spheres of plasma that have collided due to gravity.

Heavy elements such as carbon, nitrogen, and oxygen are produced by stars.

The visual aspect of the universe is shaped by star formation, which also supplies the locations for planets.

Especially in the field of astronomy.

The Cycle of a Star's Life

Stars are born within dust clouds and are found across most galaxies.

The Orion Nebula is a well-known example of such a dust cloud.

In the blazons of spiral galaxies, stars develop as an impenetrable cloud of gas.

Under the influence of the star's gravity, individual hydrogen atoms descend with accretionary speed and energy into the cloud's centre.

Deep within these clouds, slubs of sufficient mass form, causing the gas and dust to begin to collapse under their own gravitational force.

The gas is heated by the increase in energy.

The temperature rises to around 20 million degrees Fahrenheit after millions of years of this activity.

The hydrogen within the star ignites and burns in a never-ending series of nuclear events at this temperature, and the material at the centre begins to heat up.

The Sun, our nearest star, is so hot that a massive amount of hydrogen conducts a star-wide nuclear reaction, similar to that of a hydrogen bomb.

Even though it is constantly bursting in a nuclear reaction, the Sun and other stars are so massive that the explosion will take billions of years to consume all of the star's fuel.

The inward force of gravity balances the exterior pressure of the gas heated by fusion, leaving the star in hydrostatic equilibrium.

By keeping the star's temperature constant, this hydrostatic equilibrium remains balanced during the majority of the star's life.

From birth to death, and all the stages in between, the life cycle of any star would take billions of years.

That's why, to these goliaths, a human morsel of a blink of an eye doesn't seem to change anything.

Planets

A planet is a celestial body that orbits the Sun and has sufficient mass for itself-gravity to overcome rigid body forces, causing it to assume a hydrostatic equilibrium, making it round. Planets are smaller than stars. Planets in Malayalam written as ഗ്രഹങ്ങൾ

Difference Between Star and Planet or 10 difference between planet and star

Stars	Planets
The most well-known astronomical objects are stars, which are the most basic building pieces of galaxies.	In comparison, the planet is a massive natural body that revolves around the Sun or a star and does not emit energy from nuclear fusion events.
Thermonuclear fusion, which occurs at the centre of stars, produces their own light.	Planets don't have their own light, thus they reflect the Sun's.
Because of the great distance between the stars, their positions vary, and this can be seen after a long period.	Planets have a tendency to shift positions as they orbit the Sun.
Greater in size	Smaller in size
They have dot like shape	They have round like structure
A star is a massive gaseous object with a very high temperature.	There temperature is low
Because of air refraction, they glitter.	They are not twinkling.
Hydrogen, helium, and other light elements make up this substance.	Solids, liquids, or gases, or a combination of these three.
Stars travel in their own orbits, each with a substantial distance between them, and their motion can be observed after a long period.	Planets follow a specific course around the Sun as they orbit the Sun. Orbit is the name given to this journey (Elliptical orbit).
In the solar system, there is only one star, but there are trillions of stars in the galaxy.	In the solar system, there are eight planets.

NCERT Physics Notes :

Difference between Space and Universe

Space	Universe
The void that lies between celestial objects is referred to as space.	The term "universe" encompasses all physical matter and energy, as well as solar systems, planets, galaxies, and all the contents of space.
Space does not include celestial objects; only the space between them is included.	All heavenly objects are included in the universe.
Magnetic fields, electromagnetic radiation, neutrinos, dust, and cosmic rays are all present in space.	Planets, stars, galaxies, and space make up the universe.
