Suppose there were a planet in our Solar System orbiting at a distance of 0.5 AU from the Sun, and having ten times the mass and four times the radius of Earth. For reference, the Earth has a mass of 5.97 × 1024 kg and a radius of 6,378 km.

a) Calculate the density of this hypothetical planet.

b) Based on your answer from part a), what do you think this planet would be made of? Explain your reasoning.

c) Do this planet’s properties agree with the condensation theory for the formation of our Solar System? Why or why not?

Earth II is a planet in a distant solar system which is earth-like, but a little smaller than our earth. In the distance future, Earth II has been settled by bold travelers from our home planet. Very far from Earth II (effectively at R=∞), a spacecraft has run out of fuel and its kinetic energy is zero. If only the gravitational force of Earth II were to act on the spacecraft (i.e., neglect the forces from the sun and other...

What is the center of mass of our solar system? For this problem, we can make a first order approximation that the center of mass of our solar system is roughly the center of mass between our sun and the planet Jupiter (since Jupiter has more mass than all the other planets.) Is the center of mass inside the sun? The distance between the sun and Jupiter is 7.78 x 10^11m. The mass of the sun is 1.99 x 10^30kg...

The gravitational acceleration on Earth is g=9.8 m/s2. Consider a planet outside the solar system that has a mass 4 times larger than that of Earth and a radius that is also 4 times larger than that of Earth. Estimate the gravitational acceleration (in m/s2) on that planet.

Astronomers discover a planet orbiting around another star. The star is very much like our Sun, and the planet is almost a twin to Jupiter. The planet has the same mass as Jupiter, is the same distance from its star as Jupiter is from our Sun (5.2 AU), has the same orbital period (12 years), is the same temperature, and has the same density and chemical composition as Jupiter. However, when we take a close up picture of the planet,...
