The solar system has a planet with an orbital period T1b=1.51d and an orbital radius of R1b=1.6456x10^6km. Another planet in the system has an orbital radius of R1f=5.5352x10^6 km. Calculate its orbital period in days.
The planet Earth has a semi-major axis of a = 1.00 AU and an orbital period of
P= 1 sidereal year = 365.25 days = 3.156 x 10^7 s. Compute the orbital periods of bodies
orbiting the Sun with each of the following semi-major axes.
a)
a = 0.1 AU
b)
a = 10 AU
c)
a = 100 AU
d)
a = 1000 AU
e)
a = 10,000 AU
1 AU = 1.496 x 10^8 km = 1.496 x 10^11 m = 1.496 x 10^13 cm.

- Mars has two moons orbiting it. One moon is named Deimos ( terror/dread from Greek mythology). Deimos has a mass of 2(10)^15 kg and is 23,460 km from Mars. The mass of Mars is 6.42 (10) ^23 kg a) What is the gravitational force between Mars and Deimos?

- 3. The Moon has a period of 27.3 days and a mean distance of 3.90×105 km from the center of Earth. a. Use Kepler's laws to find the period of a satellite in orbit 6.70x103 km from the center of Earth. b. How far above Earth's surface is this satellite?arrow_forward(a) Jupiter's third-largest natural satellite, Io, follows an orbit with a semimajor axis of 422,000 km (4.22 ✕ 105 km) and a period of 1.77 Earth days (PIo = 1.77 d). To use Kepler's Third Law, we first must convert Io's orbital semimajor axis to astronomical units. One AU equals 150 million km (1 AU = 1.50 ✕ 108 km). Convert Io's a value to AU and record the result. aIo = AU (b) One Earth year is about 365 days. Convert Io's orbital period to Earth years and record the result. PIo = yr (c) Use the Kepler's Third Law Calculator to calculate Jupiter's mass in solar units. Record the result. MJup(Io) = MSun (d) Based on this result, Jupiter's mass is about that of the Sun. Jupiter has a similar fraction of the Sun's volume. The two objects therefore have rather similar density! In fact, Jupiter has a fairly similar composition as well: most of its mass is in the form of hydrogen and helium.arrow_forwardOn the surface of the Moon an astronaut has a weight of Fg = 190 N.
