Scientists recently confirmed that the Kepler Space Telescope has found two habitable planets (see BBC article here)
Neglecting the small issue that these planets happen to be 1200 light years away, it’s interesting that they both have a diameter which is approximately 1.5 times larger than that of the Earth (How the telescope can be that accurate with such huge distances is beyond me???).
If the diameter of these planets is 1.5 times larger, are their surface areas also 1.5 times larger?
Info needed: Diameter of Earth: 12 742 km
What happens if the diameter of these habitable planets is twice as big, three times bigger, n times bigger?
