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.

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
