Asteroids are believed to be material that never collected into a planet. An asteroid has a period of 3.6 years. Assuming the asteroid to be at the center of the planet if it had formed, how far would the planet be from the Sun?
A synchronous satellite, which always remains above the same point on a planet's equator, is put in circular orbit around Neptune so that scientists can study a surface feature. Neptune rotates once every 16.1 h. Use the data of this table to find the altitude of the satellite.
Assume these are the mass and radius of Venus. Myenus = 5 x 1024 kg, Ryenus = 6,000,000 meters.
What is the velocity required to put a satellite into stable orbit around Venus starting from the
surface of Venus so that it orbits once every 24 hours? [ignore the rotational velocity of Venus and
gravity of the Sun]
