Also regarding the moon's maria:

1) What does the term maria refer to?
2) Where does the name maria, meaning sea, come from?
3) How old are they, and what event(s) formed them?

Answer
1. Maria are large basaltic plains on our moon, Luna, that have been formed as a result of ancient volcanic eruptions
2. It is a Latin term, where "mare" mean sea.
3. The youngest ones are estimated to be 1.2 billion years old, but most range from around 3-3.5 billion years.

While 2 is not incorrect, I was thinking more along the lines that ancient astronomers thought they were seas on the lunar surface. Otherwise great!

Let's try something other than maria for now:

Question
Image
1) Identify the astronomical body.
2) How long, in Earth days, does it take this body to make an entire revolution?
3) Give a theory as to why the body moves in a retrograde rotation.

Answer (I hope)
1. Venus
2. Around the sun, 224.7; rotation, 243.02
3. Venus' axis is tilted almost 180 degrees, so it spins on its axis almost exactly opposite its orbit

1. What is the streak of light?
2. Identify it's other counterparts (You should end up with two other ones).
3. A follow-up to two... how are they differentiated?

Answer
1. A meteor
2. Comet, Asteroid? Meaning unclear
3. What I've noticed: Comets are kind of blurry (they don't give a distinct image), with a trail left behind; asteroids are more distinct; and meteors are somewhere in between. (this may not be the real answer)

That's right, but instead I wanted like meteorite and meteoroid, where a meteorite has already struck Earth while a meteoroid is not within Earth's atmosphere.
