All of the planets in our Solar System are less than a light year away, but no other planets around other stars are within that distance.
Three planets come within 100 million miles of Earth: Mercury, Venus, and Mars. However, these planets will be more than 100 million miles away depending on where they are in their orbits relative to Earth.
it not because some plants are far away from the sun so they get less light if they get less light the day will be short
Yes it does but the planets closer to the sun get more heat and the planets that are farther away get less heat. That is why Venus is hotter than our Earth and Mars is colder.
All of them do.
There are no planets at that distance from the Earth. The Earth is 8 light minutes away from the Sun. Neptune is 3 light hours from the Sun. The closest star, and therefore the closest planet outside of our solar system would be Alpha Centuri at 4.24 light years away.
No.
The planets that have less mass than Earth are Mercury, Mars and Venus. The planets that have a lower average density than Earth are all of them; Earth is the most dense planet in our solar system.
An Au is defined as the average orbital radius between the Earth and the Sun. It's a shorthand unit used to make Keplar's Laws calculations easier. Since the distance between Earth and the Sun is equal to 1 AU, all the planets between Earth and the Sun orbit less than one AU away from earth. In addition it is possible that Mars also orbits 1 AU away from Earth, but I am not certain as to weither or not it actually does.
The farther away from the sun the planet is, the more space it has to cover. Therefore, the planets distance from the sun whereas, if i am half the distance from Earth/Sun, that planet will get more energy. But if I am twice the distance from Earth/Sun, I will receive less energy.
Mercury, Venus, and Mars.
Eris is far less than a light year away. Eris varies in distance between 99 and 37 astronomical units away, which works out to 0.00059 and .00156 light years.
the earth Pluto and that's all i know
