Summary
The main difference between a star and a planet is that a star is a celestial object that emits light and heat from the nuclear forges inside its core, while a planet is an object that orbits a star, is big enough to have a gravitational force and spherical shape, and is big enough that its gravity has cleared away other objects of similar size near its orbit around the star.

Stars have a greater mass than planets and are usually much bigger and hotter.

Planets reflect some of the radiation coming from their parent star, but they do not generate their own energy.

Additionally, stars are fixed and large luminous bodies, while planets have an apparent motion of their own and move around the star in an elliptical orbit.

Summary
A star is an object, the mass of which is large enough to ignite the process of nuclear fusion. Nuclear fusion is the process by which atoms are fused to form heavier atoms. For stars, pressures and temperatures in their cores are so high that hydrogen atoms fuse to form helium atoms. This process releases so much energy that powers the star. If an object does not gain enough mass to ignite nuclear fusion, it will never become a true star.
A planet is a spherical object that orbits a star and whose mass is significant enough to clear its orbit of debris. Planets can come in different masses. In our solar system , each of the eight planets is vastly different in size and mass. Mercury is the smallest planet at only 0.055 times the mass of Earth. Jupiter is the largest planet, having a mass of 318 Earths. Jupiter may be unbelievably massive, but it is not massive enough to ignite nuclear fusion in its core.
Every star begins its life in virtually the same way. A large cloud of hydrogen clumps together and collapses under its own gravity. Stars begin their lives as small clumps of gas and dust, and as the gravitational pull increases exponentially, more and more material is drawn in, and the star increases in mass. Eventually,

• Stars are much bigger and hotter than planets, and they generate their own energy through nuclear reactions.
• Planets reflect some of the radiation coming from their parent star, but they do not generate their own energy.

Summary
What Is A star?: A star is a bright ball of gas, primarily hydrogen and helium, held together via gravity. Nuclear fusion events in its core let the star resist gravity by producing light, heat, and a low percentage of heavier elements. Stars are enormous in size and have tremendous gravitational attraction. The Sun is the star closest to Earth. The sun is a modera...
What Is A Planet?: A planet is a celestial body that orbits a star or stellar remnant and is huge enough to be spherical by its gravity but not massive enough to produce thermonuclear fusion and has eliminated the planetesimals in its vicinity. A planet is a huge astronomical body that revolves in fixed orbits around the sun. Planets do not emit their natural light, ...
Other Celestial Bodies Similar to Stars and Planets: Celestial bodies, also known as heavenly bodies, are objects in space that include the sun, moon, planets, and stars. They are a part of the enormous cosmos in which we live and are normally quite far away from us. Such objects abound in the magnificent night sky, and when viewed through a telescope, they reveal intriguing worlds of their own. Besi...

Summary
A star is a celestial body that possesses a light that causes it to reflect the light independently. On the other hand, a planet is simply a fixed celestial body with its own orbit and spins on its own axis, yet reflects the light from an external source. As planets do not have an internal light source, they only receive light from external sources, primarily the Sun. Minkowski space is usually used to solve special relativity problems, to obtain solutions.
One of the major key points that differentiate stars from planets is size. Even though planets may look gigantic in images and stars may look distant and small, stars are gigantic compared to planets. Check out the table below for a full comparison between planets and stars.

Summary
• A planet must be found orbiting a star just like Earth orbits around the Sun.
• Stars have a greater mass than planets. The gravity of all this mass is what “locks” planets into their orbits and makes them go around it when they are created.
• Some definitions state that stars are stationary while planets orbit around them. This is incorrect. Stars are also moving around the center of their galaxies.
• Planets are made of much colder elements that for the most part do not generate light. The reason why we can see planets from Earth is the same reason why we can see the Moon. They are reflecting the light from the Sun.
• If you want to get very specific, there are some exceptions to this rule. Some planets do generate small amounts of light or radiation, but it is usually too weak to be perceived at a long distance.

Summary
Stars are heavenly bodies that possess their own light and twinkle. They are fixed and large luminous body like the Sun. Planets are celestial objects, which have an apparent motion of their own and also moves around the star, in an elliptical orbit. They have their own light. They do not have their own light. Their position changes but due to substantial distance, it can be seen after a long time. There is only one star in the solar system. There are eight planets in our solar system.

Summary
• A star is a celestial object that emits light and heat from the nuclear forges inside its core.
• A planet, on the other hand, is an object that orbits a star, is big enough to have a gravitational force and spherical shape, and is big enough that its gravity has cleared away other objects of similar size near its orbit around the star.
• Ancient astronomers were able to distinguish the difference between stars and planets based on their movements throughout several nights.
• Stars in our solar system, however, move in a circular pattern around the North Star. So basically, if you want to identify celestial objects by their movement alone, you will have to chart the course of the objects you see over a series of nights.
• If the object you are tracking travels in a straight line, you are most likely tracking a planet!
• Once you’ve identified a planet, the next step is to identify the planet you are gazing at. The best way to tell the difference between the planets is to observe their color. Though not all planets in the solar system have a specific color, the most prominent plants you can see in the night appear to have a color.
