What is the difference between a planet and a star?

Identify one similarity between the formation of a star and the formation of a planet. Identify one difference?

• Answer:

  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. why planets are diffrent is because a planet is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system planets are way smaller than stars, stars are probably 10-1000's of times bigger than plants. Another thing is stars produce nuclear energy in their core so they burn and give of heat, which by far planets don't give off. The third thing is Stars have more gravity than planets so they make smaller bodies orbit around them. simalarities are they both have gravity and are formed due to gravitational pulls
