An asteroid is discovered in a nearly circular orbit around the Sun, with an orbital radius that is 2.49 times Earth's. What is the asteroid's orbital period T, its "year," in terms of Earth years? ears
An asteroid, whose mass is 2.50×10-4 times the mass of Earth, revolves in a circular orbit around the Sun at a distance that is 2 times the Earth's distance from the Sun. Calculate the period of revolution of the asteroid. Tries 0/10 What is the ratio of the kinetic energy of the asteroid to the kinetic energy of Earth?
(a) An asteroid is in an elliptical orbit around a distant star. At its closest approach, the asteroid is 0.700 AU from the star and has a speed of 54.0 km/s. When the asteroid is at its farthest distance from the star of 36.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 x 101 m. You may assume that other planets and smaller objects...
The earth moves around the sun in a nearly circular orbit of radius 1.50 1011 m. During the three summer months (an elapsed time of 7.89 106 s), the earth moves one-fourth of the distance around the sun. (a) What is the average speed of the earth? (b) What is the magnitude of the average velocity of the earth during this period?
Most asteroids orbit around the Sun at distances greater than the orbit of Mars but less than the orbit of Jupiter. The amount of time it takes an asteroid, whose average distance from the Sun is 3.80 astronomical units, to complete one orbit around the Sun is ____ years.
An asteroid is in an orbit around the sun whose closest point to the sun has a radius R and whose most distant point has a radius 9R, where R is equal to the radius of the earth's orbit = 1 AU = 1.5 x 10^11 m. 1. What is the asteroid's speed when it is closest to the sun? 2. How does this compare with the earth's orbital speed? 3. What is the period of this orbit, in years?
planet X travels in a circular motion orbit around the Sun. The radius of Planet X is twice that of Earth. The year on Planet X is 540 Earth years. The mass of Planet X is half that of Earth. The mass of the sun is 1.99*10^30 kg. The Earth's orbital distance from the Sun is 1.50*10^11 m.
The mean distance of an asteroid from the Sun is 4.10 times that of Earth from the Sun. From Kepler's law of periods, calculate the number of years required for the asteroid to make one revolution about the Sun. yr
A small spinning asteroid is in a circular orbit around a star, much like the earth's motion around our sun. The asteroid has a surface area of 7.70 m2. The total power it absorbs from the star is 4200 W. Assuming the surface is an ideal absorber and radiator, calculate the equilibrium temperature of the asteroid (in K).
Assume the earth is revolving around the sun in a circular orbit with a radius of 149,600,000km. What is the centripetal acceleration of the earth as it revolves around the sun?
