An asteroid is in a highly eccentric elliptical orbit around the Sun. The period of the asteroids orbit is 90 days. Which of the following statements is true about the possibility of a collision between this asteroid and the Earth? (a) There is no possible danger of a collision (b) There is a possibility of a collision. (c) There is not enough information to determine whether there is a danger of a collision.
Comet P/1999 R1 has a perihelion of 0.0570 AU and aphelion of 4.99 AU. Using the results of the previous problem, find its speed at aphelion. (Hint: The expression is for the perihelion. Use symmetry ot rewrite the expression for aphelion.)
What is the orbital period of a satellite orbiting just above the surface of the asteroid in Problem 11?
A Molniya orbit is a highly eccentric orbit of a communication satellite so as to provide continuous communications coverage for Scandinavian countries and adjacent Russia. The orbit is positioned so that these countries have the satellite in view for extended periods in time (see below). If a satellite in such an orbit has an apogee at 40,000.0 km as measured from the center of Earth and a velocity of 3.0 km/s, what would be its velocity at perigee measured at 200.0 km altitude?
Saturns ring system forms a relatively thin, circular disk in the equatorial plane of the planet. The inner radius of the ring system is approximately 92,000 km from the center of the planet, and the outer edge is about 137,000 km from the center of the planet. The mass of Saturn itself is 5.68 1026 kg. a. What is the period of a particle in the outer edge compared with the period of a particle in the inner edge? b. How long does it take a particle in the inner edge to move once around Saturn? c. While this inner-edge particle is completing one orbit abound Saturn, how far around Saturn does a particle on the outer edge move?
The perihelion of the comet LINEAR–Skiff is 2.12 AU and the aphelion is 6.11 AU. Given that its speed at perihelion is 25 km/s, what is the speed (in km/s) at aphelion (1 AU = 1.496 ✕ 1011 m)? (Hint: You may use either conservation of energy or angular momentum, but the latter is much easier.)_________ km/s
The perihelion of the comet La Sagra is 1.37 AU and the aphelion is 7.49 AU. Given that its speed at perihelion is 33 km/s, what is the speed (in km/s) at aphelion (1 AU = 1.496 ✕ 1011 m)? (Hint: You may use either conservation of energy or angular momentum, but the latter is much easier.)
Comet Halley orbits the Sun with a period of 76 years and in 1986, had a distance of closest approach to the Sun, its perihelion distanc Rp, of 8.9x1010 m. a) What is the comet's farthest distance from the Sun, which is called its aphelion distance Ra? b) What is the eccentricity of the orbit of comet Halley?
Consider a spherical asteroid with radius 28.2 km and mass of 5.69 × 1018 kg. Suppose the asteroid spins about an axis through its center, like the Earth, with a rotational period T. The smallest value T can have before loose rocks on the asteroid's equator begin to fly off the surface is (enter your answer with three significant figures)
On December 25, 2004, the Huygens probe separated from the Cassini spacecraft orbiting Saturn and began a 22 day journey to Saturn’s moon Titan, on whose surface it landed. Besides the data in Appendix F, it is useful to know that Titan is 1.22 * 10^6 km from the center of Saturn and has a mass of 1.35 * 10^23 kg and a diameter of 5150 km. At what distance from Titan should the gravitational pull of Titan the gravitational pull of Saturn?
An asteroid, whose mass is 1.9 × 10-4 times the mass of Earth, revolves in a circular orbit around the Sun at a distance that is 3.2 times the Earth's distance from the Sun. (a) Calculate the period of revolution of the asteroid in years. (b) What is the ratio of the kinetic energy of the asteroid to the kinetic energy of Earth?
