An asteroid orbits the sun in a circle with a period P of 12 years. About how far from the Sun is it? (Remember that P2 = a3, and the Earth goes around the Sun with P = 1 year and a = 1 AU)
If the radius of Mercury is ~2,440 km, what is the required tangential orbital velocity needed to maintain a 100 kg satellite 1,500 km from the planet’s surface? (The mass of Mercury is Mm = 3.3 x 1023 kg)
Jupiter has a mass of 1.9×10^27 kg, a radius of 7.1×10^4 km and one day lasts 9 hours and 55 minutes. How many times is the force of gravity bigger on Jupiters equator comared to Earth?

- "They were in Lucky's ship, the Shooting Star, which was in orbit around Jupiter, once it had matched its speed with Jupiter Nine, the outermost satellite of the gigantic planet. The satellite remained stationary at a distance of 1,500 km from the ship. Officially, its name was Adrastea, but except for the largest and closest ones, Jupiter's satellites were usually known by numbers. Jupiter Nine was only 142 km in diameter, and was really just an asteroid, but it seemed larger than distant Jupiter at 23 million km" (actually the mean distance from Adrastea to Jupiter is R = 128924 km and its diameter of 16 km).
