How do you find the orbital period of AU?
If the size of the orbit (a) is expressed in astronomical units (1 AU equals the average distance between the Earth and Sun) and the period (P) is measured in years, then Kepler’s Third Law says P2 = a3. where P is in Earth years, a is in AU and M is the mass of the central object in units of the mass of the Sun.
What is the orbital period of Caprica?
Caprica is in the third orbit around the Helios Alpha star and shares its orbit with the planet Gemenon. They revolve around their common barycenter, or center-of-gravity, with an orbital period of 28.2 days.
What is the planet Caprica?
Caprica is a planet settled by the Capricorn tribe of Kobol. Its capital is Caprica City. Caprica is the most prosperous of the Twelve Colonies. The lush and beautiful world of Caprica was largely undeveloped for centuries, but it is now the undisputed center of colonial politics, culture, art and education.

Why is erosion more effective on earth than on Venus or Mars?
Why is erosion more effective on Earth than on Venus or Mars? Erosion on Earth arises primarily from processes involving water, but also from atmospheric winds. Venus has very little surface wind because of its slow rotation, and wind on Mars does little damage because of the low atmospheric pressure.
Which planet has the most erosion?
Mars has experienced significant bombardment. The southern hemisphere is more heavily cratered than the northern hemisphere. Winds are the main erosional force on Mars and windblown dust and soil erode craters over time.
Is there erosion on the moon?
Unlike on Earth, there is no erosion by wind or water on the moon because it has no atmosphere and all the water on the surface is frozen as ice. Also, there is no volcanic activity on the moon to change the lunar surface features. Nothing gets washed away, and nothing gets folded back inside.
Can you leave footprints on the moon?
Yes there are, even though nobody has stepped on the lunar surface since the last Apollo mission in 1972. The footsteps will be there for many years to come too. The Moon is geologically dead so the marks won’t be wiped out by earthquakes or volcanoes. Neither is there any wind to disturb them or rain to erode them.
Do footprints stay on the moon?
An astronaut’s footprint can last a million years on the surface of the moon. It may have been decades since we last set foot on the moon, but its surface is still marked with the historic footprints of the 12 astronauts who stomped across it. That’s because the moon has no atmosphere.
What is a moon crater called?
The majority of named lunar craters are satellite craters: their names consist of the name of a nearby named crater and a capital letter (for example, Copernicus A, Copernicus B, Copernicus C and so on). Lunar crater chains are usually named after a nearby crater.
What is the big spot on the moon?
The surface of the Moon is covered in huge dark spots, visible from Earth even with the naked eye. These patches are known as maria – a Latin word meaning ‘seas’.
What’s at the center of the moon?
At the center is the Moon’s dense, metallic core. The core is largely composed of iron and some nickel. The inner core is a solid mass about 480 km in diameter. Surrounding the solid inner core is a fluid outer core, that brings the total diameter of the core to about 660 km.
Is the center of the moon hot?
What is the Moon made of? At its very centre, the Moon has a solid iron core with a temperature of between 1,327°C and 1427°C. This is hot enough to create a surrounding molten liquid iron outer core, but not hot enough to warm the surface. The mantle which envelops the core is roughly 1,000 kilometres thick.
