What are the requirements for a habitable moon?

Kepler's laws show the effects of gravity on orbits. They apply to any object that orbits another: planets orbiting the Sun, moons orbiting a planet, ... The orbital period of a planet can be calculated using Kepler's Third Law, which states that the square of the orbital period (T) of a planet is directly ... May 23, 2017 ... It shows, using harmony, rhythm and visuals, the relationships between the orbits of the seven planets around TRAPPIST-1, a dwarf star about 40 ... An extrasolar planet, or exoplanet, is a planet outside of our solar system that orbits a star other than our Sun. ... planet's orbital period depends only on its orbital radius. ... Rank the graphs from left to right based on the mass of the extrasolar planet that orbits the star ... Jan 9, 2020 ...

Astronomers have discovered three small moons at the farthest planets of our solar system — two circling Neptune and one around Uranus. In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object [1] such as the trajectory of a planet around a star. Every moon in S4 orbits planet Alpha. REASONING: Every moon orbits a planet in a solar system. ANALYSIS: This isn't a very good argument. Elliptical orbits are a lot more important than circular orbits. A spaceship leaving earth and going in a circular orbit won't get very far.
