What changes would happen if the earths revolutions around the sun took 2 years?

Answer 1

To get this result, and assuming the Sun doesn't change, either the Earth would have to rotate more slowly (longer day-night periods), or the Earth would have to be further from the Sun (longer years - also, further away from the Sun and therefore colder).

Answer 2

If the Earth's revolution around the sun took 2 years instead of 1, the seasons would be twice as long, with summer and winter each lasting a year. This would likely lead to more extreme seasonal variations in temperature and weather patterns. Plant and animal life cycles would also be adapted to the longer seasonal cycle.

Answer 3

The Earth would have the same relationship with the sun as the Moon has with Earth -- namely, one side of the Earth would always face the sun, and one side would always be in the dark.

Answer 4

Winter would be colder and longer. Summer would be longer and hotter and pool business would boom.
