What sources of data might help us determine more about how Earth's Moon formed?
The iron meteorite that created Barringer Crater (Arizona) was 50 m in diameter. It caused a crater 1.2 km (1200 m) in diameter, that is, 24 times bigger than the impactor. Keeping in mind that the size of the crater depends on many factors, such as the type of rocks present in the area, estimate the approximate size of the impactor that produced Mare Serenitatis.
Hellas Planitia includes the word "planitia" which is the latin word for "plain" in its name.
The name would seem to indicate thats Hellas Planitia is a low lying plain, yet it is clearly a crater, and a very large one at that.
The most probable reason for this discrepancy in its name is because:
a. It is a simple naming error that for some reason has so far escaped correction.
b. There is a disagreement among astronomers about the true nature of Hellas Planitia.
c. Its true nature was not apparent over 100 years ago when it was observed using ground based telescopes.
d. Astronomers really know its true nature and misconceptions among the public among the public are not of great concern to them.

What sort of features would you look for on the outer planet moons to find evidence of such collisions? (As an extra bonus, can you find any images of such features on a moon like Callisto?

- Based on the physical aspects of Catena Mendeleev, what is the most plausible explanation for how crater chains are formed on the Moon? a. these craters chains are formed by a series of impacts from a passing comet or asteroid that just passed to close too the Moon and ended up colliding with the Moon b. they are the result of surface collapse due to the prescence of an underground fault c. they are primarily the result of secondary fragments hitting the lunar surface from an initially from an larger impact fragment that resulted in another larger, distant craterarrow_forward3arrow_forwardhelppparrow_forward
