None of the planets is a fusion reactor.

The sun is a fusion reactor but it is not a planet.

Does star gives off heat?

Yes, stars give off heat as a result of the nuclear fusion processes occurring in their cores. This fusion generates immense amounts of energy, which is released in the form of light and heat. The heat radiates outward, warming the surrounding space and any nearby celestial bodies, including planets. The Sun, for example, emits heat that sustains life on Earth.


How many planets actually fit in the sun?

All the planets in the solar system would fit in the sun with lots of space left over.


Which planets have the most space between them?

The planets that have the most space between them are mercury and Pluto.


What characteristic of the sun is MOST responsible for keeping the planets in orbit?

The characteristic of the Sun that is most responsible for keeping the planets in orbit is its immense gravitational pull. The Sun's mass, which is about 99.86% of the total mass of the solar system, generates a strong gravitational force that attracts the planets, keeping them in elliptical orbits. This gravitational interaction balances the planets' inertia as they move through space, preventing them from drifting away.


How does the sun in space stay in one place?

The sun appears to stay in one place in the solar system because it is the central point around which the planets, including Earth, orbit due to its immense gravitational pull. The sun's gravity keeps the planets in stable orbits, preventing them from drifting away into space. While the sun itself is moving through the Milky Way galaxy, its position relative to the planets remains relatively constant over human timescales.

Is the Sun an immense fusion reactor in space?

yeah, exactly


What holds up the planets?

Planets are held in orbit around the Sun by the force of gravity. Gravity is the attractive force between two objects with mass, and the Sun's immense mass keeps the planets in their orbits.

What is the space velocity and space time in tubular flow reactor?

Space velocity is the number of reactors treated in unit time while space time is the time required to treat a reactor.


How is the sun still on fire when it's cold in outer space?

To start off, space is not necessarily cold. Conditions in space can be very hot near a hot object such as the sun. Second, the sun is not truly a fire, but a giant, natural thermonuclear reactor. The heat generate by the fusion of hydrogen into helium drives more fusion, which in turn generates more heat, so the sun sustains itself in this manner.


What is astronomical?

It means extremely large, exceedingly great and immense. Or relating to astronomy, the science that deals with the material universe beyond the Earth's atmosphere


Why do planets have to be in space?

If they aren't in space, then where else can they be?


How is the formation of stars different from the formation of planets?

Planets are pieces of material that orbit a star such as the earth orbits the sun. Stars are 'suns' and are distributed throughout the universe. Stars are much larger than planets hence the reason that at night stars can be seen in the sky and planets cant even though the stars are much futher away than the other planets in our solar system.


What do the planets have to do with astronomy?

Astronomy is all about the things in outer space and planets are in outer space.
