Why do some astronomers object to the new definition of a planet that was adopted in 2006? A. New space missions show that Pluto is much larger than originally thought. B. By this definition, Earth, Jupiter, and other planets should not be considered planets. C. There was never a vote on whether to adopt the new definition or not. D. It means that we now technically have over 100 planets.

What would the mass of the Sun have to be if Pluto (the outermost planet most of the time) were to have the same orbital speed that Mercury (the innermost planet) has now? The orbital speeds of Mercury and Pluto are 47.9 km/s and 4.74 km/s respectively. Express your answer in terms of the Sun's current mass MS, and assume circular orbits.

A dwarf planet with mass M = 2.43 x 1016 kg and radius R = 2360 km is crashed into by a large comet. The dwarf planet initially has a day with length 12 hours. The comet hits the planet at its equator and at an angle of 0 = 80° with the radius of the planet, as shown in the view of the planet looking above from the North Pole. The speed of the comet is V comet =...

In our derivation of Kepler's laws, we assumed the only force on
a planet is due to the Sun. In a real solar system, however, the
gravitational forces from the other planets can sometimes be
important. Calculate the gravitational force of Jupiter on the
Earth. Do the calculations for the cases when Jupiter is both
closest (Fc) to and farthest
(Ff) from the Earth (see the figure below).

1 (10 pts). In 1601 the German astronomer Johannes Kepler became director of the Prague Observatory. Kepler had been helping Tycho Brache in collecting 13 years of observations on relative motion of the planet Mars. By 1609, Kepler had formulated his first two laws of planetary motion: i. Each planet moves on an ellipse with the sun at one focus. ii. For each planet, the line from the sun to the planet sweeps out equal areas is equal times. Kepler's...
