Actually I dont know, but I guess the rate of everything happeningnow would be twice as fast.
if it was twice as massive, earth probably have burned, noone would be here, and surviving would be a 1 out of 100,000
Mars has roughly twice the Earth's period of revolution.
If the sun was replaced by a star with twice as much mass the gravitational force would be unbalanced and the new sun would burn the earth because if the gravitational force cannot hold than the sun would plummet towards the earth and burn it.
No, Mars isn't twice the size of the Earth. The equatorial diameter of the Earth is 7,926 mi (12,760 km), while the equatorial diameter of Mars is 4,220 mi (6,792 km). So we can tell that the Earth is twice the size of Mars, not the other way round.
umm... no. The moon is about 4 times smaller than the Earth
No, only once. Exactly.
No. The moon rotates once for every orbit it makes around Earth.
A Martian day is only 40 minutes longer than an Earth day, but its year is almost twice as long as ours.
i will be twice as heavy

Double
If Earth had twice as much oxygen as it does, fires would start easier and burn hotter. Arthropods (insects, spiders and the like) could be a good deal larger than they are now.

Mars takes longer to rotate around the sun than Earth. Since it takes Mars almost twice as long as earth to make a rotation around the sun, you are half your age. Less rotations, less years
Days and nights would be twice as long, obviously. The slower rotation would have impacts on the weather, much of which is driven by the Earth spinning. Days would be warmer and nights cooler, for example, because each spot on the Earth would have twice as long in the sunshine to heat up, with twice as long at night for heat to radiate away.
They are just two separate events (holidays, events, celebrations, whatever you want to call them) that happen to be on similar topics, but still fall on different days. (Plus, it helps the earth twice!)
