What is the main difference between a planet and a star?

Answer 1

Difference Between a Planet and a StarA star contains much more mass than a planet, enough that gravitational forces have compressed the matter enough to start a fusion reaction at the nuclear level, radiating the resultant energy out.

A planet orbits a star in a regular manner. The sum of a star and it's orbiting planets is called a Solar System.

Stars are always much bigger than planets. Also, their content is different. stars are made of mostly hydrogen, which they push together to form helium. this is then pushed together to form other elements which are blown into space. (although one star nicknamed Lucy has got alot of carbon in its core, which because of the pressure has formed a diamond which is a billion billion carats.) planets are different. although they may be made of gas, like Jupiter, they are different gases to the ones in stars. also, it is actually very unlikely that it is made from gases. it is usually molten iron and rock.

A star is a burning mass of (mainly) hydrogen and helium. The outer planets are also made out of hydrogen and helium. Neptune and Uranus theirs also have methane,hydrogen, and helium in it that's why both planets are blue.

A planet is a body which moves in an orbit around a star.

A planet (of any sort, dwarf or other) is defined as "any celestial body which orbits a star." The earth is a planet.

A star is typically a big, burning, ball of gas around which planets tend to orbit. (except when it goes out, then it is a black hole or a neutron star.) The sun is a star.

Fun fact: The only place gold comes from is supernovas. All gold is made in supernovas.

Answer 2

A star is massive ball of fire and luminous sphere of plasma held together by gravity . a star emits its own light and energy and in our earth, sun ( a star ) is the main source of energy .

A planet is the celestial body orbiting a star or any other stellar remnant which is massive enough to be rounded by its own gravity . Planets can't emit their own light and energy .

Answer 4

The main difference between a planet and a star is that stars produce their own light through nuclear fusion, while planets do not generate light. Stars are much larger and primarily made up of gases, while planets are smaller rocky or gaseous bodies that orbit stars.

Answer 5

A star generates its own heat and light and is generally much more massive than a planet which only orbits round a star and reflects its light.

Answer 6

Stars undergo nuclear reactions that burn hydrogen in their cores. Planets don't do this. Stars are actually big balls of gas, like the sun.

Answer 7

A star is self luminous.
