Because the earth's orbit is slightly elliptical, the earth actually gets closer to the sun during part of the year. When the earth is closer to the sun its orbital speed is
greater than when the earth is farthest away from the sun. | |
less than when the earth is farthest away from the sun. | |
the same as when the earth is farthest away from the sun. |

A satellite in an elliptical orbit around Earth has a speed of 8202 m/s when it is at perigee, the position in the orbit closest to Earth. At this position, the satellite is 122 km above Earth's surface. Part A How far above the ground is the satellite when it is at apogee, the position in its orbit farthest from Earth? Express your answer with the appropriate units.
A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 5 1010 m (inside the orbit of Mercury), at which point its speed is 9 104 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed when it is 6 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.) speed = ______m/s
A comet moves about the Sun in an elliptical orbit, with its closest approach to the Sun being about 0.620 AU and its greatest distance from the sun being 35.5 AU (1 AU = the Earth-Sun distance). If the comet's speed at closest approach is 54.0 km/s, what is its speed when it is farthest from the Sun? (The gravitational force exerted by the Sun on the comet is parallel to the moment arm, so exerts no torque. Therefore, angular...
A satellite is put into an elliptical orbit around the Earth. When the satellite is at its perigee, its closest approach to the Earth, its height above the ground is hp = 217.0 km and it is moving with a speed of vp = 8.850 km/s. When the satellite reaches its apogee, at its farthest point from the Earth, what is its height ha above the ground?
A satellite is put into an elliptical orbit around the Earth. When the satellite is at its perigee, its closest approach to the Earth, its height above the ground is h_p = 225.0 km and it is moving with a speed of v_p = 9.850 km/s. When the satellite reaches its apogee, at its farthest point from the Earth, what is its height ha above the ground?
The semimajor axis of Mars orbit is about 1.52 astronomical units (au), where an au is the Earth's average distance from the Sun, meaning the semimajor axis of Earth's orbit is 1 au. To go from Earth to Mars and use the least energy from rocket fuel, the orbit has a semimajor axis of 1.26 au and an eccentricity of about 0.21. Starting at Earth's orbit, to follow this path we give the spacecraft an orbital velocity of 40 km/s. ...

consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 300 km above the earth's surface; at the high point or apogee, it is 2500 km above the earth's surface. Part A: find ratio of the spacecraft's speed at perigee to its speed at apogee? (Vperigee / Vapogee) = ..... Part B: find the speed at the apogee? V apogee = ........ m/s Part C: find speed at perigee?...
(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...
An exoplanet is in an elliptical orbit around a distant star. At its closest approach, the exoplanet is 0.530 AU from the star and has a speed of 54.0 km/s. When the exoplanet is at its farthest distance from the star of 33.0 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 ✕ 1011 m. You may assume that other planets and smaller objects in...
