The final stage of the accretion of the Earth involved a giant impact between the proto-Earth and a Mars-sized object, known as Theia. If the final impact velocity was 10000ms-1 calculate the maximum temperature rise in the Earth if all the heat generated by the giant impact was spread rapidly and uniformly throughout the whole
Astronomers have discovered a planetary system orbiting a star, which is at a distance of 5.4 x 10^19 m from the earth.
