In a solar system, a planet is circulating the sun with T = 667days, the sunlight travels 2.54 hours from the sum to the planet. Find the mass of the sun.

In a solar system, the mass of the sun M = 2.36×1032kg, a planet is circulating the sun with a period T and the sunlight travels 2.54 hours from the sum to the planet. Find T.

Answer #1

G= gravitational constant= 6.674x10-11

r= distance between sun and planet

r = time required to light to reach from sun to planetx speed of light

Speed of light= 3x108m/s

r = hourx 3600x3x108 second

M= mass of sun

T= time in second required to planet for 1 revolution

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)...

Explore the dependence of sunlight on earth-sun distance. The solar constant, S_0 is the solar radiation at zero zenith angle at the mean earth-sun distance, R_m. As we learned in class the intensity of solar radiation decreases with the square of the distance. Use matlab to devise a function that calculates the daily averaged solar radiation as it depends on earth-sun distance (ignore seasonal changes in the sun's angle) through the course of one year. Use for the eccentricity the...

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 17000 km and its rotation period to be 22.8 hours. You have previously determined that the planet orbits 240000000 km from its star with a period of 500 Earth days. Once on the surface you find that the free-fall acceleration is 11.8 m/s22. What is the mass of the planet? What is the mass of...

I was on a planet and I carefully observed the star of that solar system (its sun) and it had starspots that looked to travel from the bottom of the star to the top of the star. What does that tell me about the star and why?
