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.

Suppose that you have a planet in a circular orbit about a star with the mass of the Sun. The orbital speed is 141 km/s. If you could increase the planet’s speed, what speed would you need to make it to escape the gravitational pull of its parent star?

Planetary Speed help: According to Kepler’s Third Law, planets closer to the sun have shorter years. We might ask the question, “Is this because they move faster, or because they don’t have as far to go?” Let’s investigate. Speed is distance divided by time, so if we know how far a planet travels and how long it takes, we can calculate speed. Look up the period and orbital distance (in years and AU, respectively) of Mercury, Venus and Earth. Assuming...

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 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). What is the mass of the star?

1) Planet Velocities and Energy (33 pts) We talked about how planet formation involves the collisions of bodies (planetesimals, embryos) leading to the growth (and heating) of a planet. Let's think about the velocities and energies involved here. a) The speed of a body in its orbit around the Sun is given by the equation: Here Vis the speed of the body in m/s, G is the gravitational constant,...

6. A star of mass 1.4M SuN (is the Sun's mass, a convenient mass unit in Astronomy) is a great distance from another star of equal mass and is approaching the second star at v 680km /s. The two stars undergo a close encounter (considered a collision) and much later the first star is moving at a θ-350 to its initial direction. In the frame of reference in which the second star is initially at rest v2, 0, find the...
