The sun of galaxy X has a diameter of about 796,000 mi with a maximum distance from Planet X's
surface of about 78,700,000 mi. Planet X's moon has a diameter of 2,731 mi. For a total solar eclipse
to occur, the moon must pass between the sun and Planet X. The moon must also be close enough to
Planet X for the moon's umbra (shadow) to reach the surface of Planet X.
The maximum distance that the moon can be from Planet X and still have a total solar eclipse occur i
(Round to the nearest thousand as needed )
Two planets, planet A and planet B, have the same surface gravity. However, planet B has twice the radius of planet A. How does the mass of planet B compare to the mass of
planet A?
The mass of planet B is four times the mass of planet A.
The mass of planet B is equal to the mass of planet A.
The mass of planet B is one-half the mass of planet A.
The mass of planet B is twice the mass of planet A.
The mass of planet B is one-fourth the mass of planet A.
Earth is about 150 million kilometers from the Sun (1 Astronomical Unit, or AU), and the apparent brightness of the Sun in our sky is about 1300 watts/m^2.
Using these two facts and the inverse square law for light, determine the apparent brightness that we would measure for the Sun if we were located at the following positions.
a) At the orbit of Venus (67 million km from the Sun).
b) At the orbit of Jupiter (780 million km from the Sun).
c) At the mean distance of Pluto (40 Astronomical Units).

So a planet that is twice as far from the Sun as Earth receives (1/2)2=0.25 times (25%) as much light and a planet that is three times as far from the Sun receives (1/3)2=0.11 times (11%) as much light.
