A number of gas giant planets orbiting other stars at distances less than 1 A.U. have been discovered. Because of their proximity to their parent stars, and their compositional similarity to Jupiter, they have been labeled “Hot Jupiters”. The orbital radius of one of these planets is 0.06 A.U. with average orbital speed 600 km/sec. What is the length of this planet’s year in Earth (solar) days? Estimate the mass, M, of its parent star in terms of the mass of the sun (M) using Newton’s first form of Kepler’s 3rd Law. Calculate the star’s luminosity, L, in terms of the luminosity of the sun (L☉), Note: (LL=MM4where L ~ 4 × 1026 W ). The radius of this planet is 1.5 times the radius of Jupiter. Assuming its equilibrium temperature is the temperature at which the planet radiates as much energy as it receives from its star, estimate the temperature of the planet. The value of the planet’s albedo is 0.8. (NOTE: The intensity of the star’s radiant power at a distance d from the star is…
Please answer the equation step by step and include a proper diagram if needed. Usse gravity as 9.8m/s^2. 4. Mars and Earth, at their closest theoretical positions, are 54.6 million km apart. The mass of Earth is 5.97 x 10 kg, and the mass of Mars is 6.39 x 10ª kg. A satellite of mass 9550 kg is to be placed such that the forces of gravity between the satellite and the two planets are equal in magnitude. Determine two possible locations for this to occur.

2. In a binary star system, the two stars orbit the center of mass of the system. If both stars have the same mass M, the center of mass will be midway between the stars. Assume the orbital radius is R. Answer in terms of G, M and R. a. Determine the orbital speed of the stars. (Your answer should not be the same as the answer for 1b.) Note that the Earth and moon also actually both orbit around the center of mass of the Earth-moon system. However, the Earth is so much more massive than the moon that the center of mass is very close to the center of the Earth and as an approximation we say the moon orbits around the Earth. b. A space probe is exactly halfway between the two stars. Determine the minimum speed the space probe must be moving so that it can escape from the binary star-that is the space probe can just reach an infinite distance away from the stars. This speed is called the escape speed. C. * We want to just reach infinity. This means we will have zero speed at infinity.…
