Question
The angle between two lines drawn from a point on Earth to two opposite sides of the Moon make an angle of 0.5 degrees.
If you do the same thing for the two opposite ends of Andromeda (as shown above), you find an angle of 5 degrees.
Let's assume Andromeda and the Moon are equally far away from our location on Earth (of course that's wrong, but how are we supposed to know?) -
then how much larger would the diameter of Andromeda be (as indicated by the arrows at the top), compared to the diameter of the Moon?
Pick the answer that's closest to what you get under this hypothetical assumption:
A. Equal Diameter
B. Twice
C. Five times
D. Ten times

Jupiter's orbit is about 5 Astronomical Units from the Sun. Suppose that the gravitational force between the Earth and the Sun is equal to 50,000 N (it's way more than that but we are just pretending here).

- How many orders of magnitude do you need to grow in spatial scale (size) to form a planet? Let's take the extreme ends of this scale, from a dust particle of radius a = 10-6m to the gas giant Jupiter (you can round up its radius to the nearest ten to keep it simple). What else has this difference in order of magnitude? Maybe pick something that's not a length scale.
