Assume that star A and star B have the same mass and each moves in a small circular path in response to an orbiting planet. Star B's path takes only half the time to go all the way around. What is the orbital radius of Star B's planet? Express it as a ratio to the orbital radius of Star A's planet.

Hint: Kepler's 3rd law relates a planet's orbital period to its orbital radius. Notice that the two stars have the same mass.

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,...

7. Two satellites are moving around Earth following orbits of the same radius. Satellite 1 has mass equal to half of mass of satellite 2. We can conclude that: Speed of satellite 1 is twice as big as speed of satellite 2. Speed of satellite 1 is half of speed of satellite 2. Speed of satellite 1 is the same as speed of satellite 2. Speed of satellite 1 in fours times speed of satellite 2. Speed of satellite 1...

A binary pulsar is a system of two neutron stars of equal mass (each about 1.4 times the mass of the sun and a radius of 10km). A particular binary pulsar has two neutron stars orbiting around their center of mass, and separated by a (center to center) distance of d= 7.0*10^8m. Assume the orbit is circular. a) Calculate the orbital speed of the stars in meters/second. b) Calculate the magnitude of the centripetal acceleration of one of the stars...

A satellite circles the earth in an orbit whose radius is 3.14 times the earth's radius. The earth's mass is 5.98 x 1024 kg, and its radius is 6.38 x 106 m. What is the period of the satellite? Two newly discovered planets follow circular orbits around a star in a distant part of the galaxy. The orbital speeds of the planets are determined to be 44.6 km/s and 59.9 km/s. The slower planet's orbital period is 8.88 years. (a)...

Suppose we find a planet with an orbital period of 200 days around a star with the same mass as the Sun, but only 75 percent as luminous. What is the planet’s semi-major axis, in AU? For the planet in the problem above, how many times more flux does it receive, relative to Earth? (If you find that the flux is less than that of Earth, express your answer as a decimal. For example, if the planet receives half as...

(b) If a meteoroid passes through the system's center of mass perpendicular to their orbital plane, what minimum speed must it have at the center of mass if it is to escape to “infinity” from the two-star system?
