Asteroid Ida was photographed by the Galileo spacecraft in 1993, and the photograph revealed that the asteroid has a small moon, which has been named Dactyl. From the dimensions of Ida and its general features, one can estimate the mass of Ida to be 4.5 x 1016 kg, and the distance between Dactyl and Ida is approximately 90 km. Assuming a circular orbit, what would be the orbital speed of Dactyl? Hint: Like the previous question, only backwards.

In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term “hot Jupiter”). The orbit was just 1/9 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). (a) What is the mass of the star? Express your answer in kilograms and as a multiple of our sun’s mass. (b) How fast (in km>s) is this planet moving?
O Jupiter's third-largest natural satellite, lo, follows an orbit with a semimajor axis of 422,000 km (4.22 × 105 km) and a period of 1.77 Earth days (Plo = 1.77 d). To use Kepler's Third Law, we first must convert lo's orbital semimajor axis to astronomical units. One AU equals 150 million km (1 AU = 1.50 x 108 km). Convert lo's a value to AU and record the result. alo = AU

The orbital period of the Earth and Mars are Pg = 365.26 d and P respectively. Assuming circular orbits, the synodic period P, for two planets to be at the same angular position from the Sun can be found using the equation 1 = 686.97 d, %3D Pe Pe a) The last opposition of Mars occurred on 13 Oct 2020. Using the information above, calculate the interval between two consecutive Martian oppositions, and estimate the date of its next opposition. b) It is said that Mars at oppositions near its perihelion occur roughly once every 15 years, with the last event occurring on 27 Jul 2018.

Suppose an asteroid has a tiny moon orbiting around it (which does occur). If the moon is 1.1 km wide, is 142 km from the center of the asteroid (which is 36 km in diameter), and assuming the moon has a circular orbit around the asteroid of period 36 hours, what is the mass of the asteroid? m = kg [Note: Use exponential notation for your answer with a format "9.99E12" for 9.99 x 1012.] What would the radius of the orbit of the same tiny moon be if it had an orbital period of 50.9 hours? Give your answer in km: R = km What is the density of the asteroid? Recall that density is mass per unit volume. The volume of the asteroid can be calculated based on its diameter (assume it is spherical in shape). Р kg/m³
