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?

suppose a planet with three times the mass of earth is orbiting a star that has three times the mass of the sun at an average orbital radius that is three times larger than earths orbital radius. how big is the gravitational force that the star exerts on the planet compared to the gravitational force that the sun exerts on the earth?

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.

We know that most of the mass (>99%) of the solar system is in the Sun. Is this consistent with the masses you calculated in the first table, and the solar system rotation curve? Explain your answer.

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,...

Kepler’s Laws of Planetary Motion: 1. A newly discovered exoplanetary system has a planet orbiting its host star at 50 times the distance from the Earth to the sun. If the orbital period of the planet is 40 Earth years, what is the mass of the host star? 2. The mass of the Earth is approximately 6 × 1026 kg. If the moon takes 27 days to orbit the Earth, how far is the moon from the Earth? 3. A...

Kepler 1606b is an exoplanet: a planet orbiting a star different than our own. Named for the star it orbits (Kepler 1606, a star about 3000 light-years away), it was discovered in the year 2016 by the Kepler space telescope. Kepler 1606b orbits its star a little bit closer than the Earth's orbit to the Sun, at a distance of 0.64⋅rearth, where rearth=1.50×1011 m is the radius of Earth's orbit. The star Kepler 1606 is bit cooler than our Sun,...

Venus is our closest neighbor in the solar system. However, due to a rampant green house effect (the atmosphere consists mostly of CO2), its average surface temperature is 864 degrees F. Still, while it may be a while before we can visit Venus, radar-equipped satellites have recently mapped out its surface and measured its radius. QUESTION 1: The mass of Venus is 4.87×10^24 kg and average radius is 6,052 km. What is the acceleration due to gravity (g) on its...

Our solar system is roughly 2.28 x 1020 m away from the center of the Milky Way galaxy, and the system is moving at roughly 227.7 km/s around the galaxy's center. Since most of the galaxy's mass is near its center (and we are on an outer arm of this spiral galaxy), let's model the galaxy has a spherical mass distribution (like a single, giant star that our system is orbiting around). What is the mass of the galaxy (according...
