mercury rotates 3 times in 2 of its years.

intensity gets smaller, as the radio waves went out they got bigger so only a part of it hit the planet mercury.

the five slices proved that mercury was rotating when the radio waves hit it.

Tunguska

I think Tunguska was a nuclear explosion and not a meteor or a comet.

1. 100 times the size of the bomb dropped on Hiroshima
2. blasted outward of ground zero.
3.knocked over an estimate of 80 million trees.

mars

1. mars is 3 feet away and earth is 2 feet away and i believe this is correct b/c its the same ratio from Ma's room to the nurses' office as it is from the sun to Pluto.
2.i would b .28 years old on mars. it takes longer to rotate around the sun so it would not be the same as on earth
3.i would be 75.4 pounds on mars and the most i would weigh would be on 472.8 on Jupiter. this happens because the gravity pull is different.
