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.
Tutorial
Based on the orbital properties of Uranus, how far across the sky in arc seconds does it travel in one Earth
day? The average orbital radius is 2.88 x 109 km and the period is 84.0 years. (Assume Uranus and the Earth
are at the closest point to one another in their orbits.)
How many full Moons does this distance cover if the Moon has an angular diameter of 0.5 degrees?
Part 1 of 4
We first need to determine how fast the planet is moving across the sky. If we know the period and the
distance between the Sun and the planet we can calculate the velocity using:
2ar
which will tell us how many kilometers the planet travels in a day if we convert the period into days.
