1. The Earth is moving around the Sun along an orbit that is approximately circular. The radius of the orbit is 150 million kilometers. The Earth can complete a full circle in approximately 365.25 days (that is, one year). Within half a year, what is (a) the average velocity and (b) the average speed of the Earth relative to the Sun? Express your answers in kilometers per second, km/s. (Hint: draw a diagram of the orbit.) 2. Spider-Man jumped off...

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...

1. Earth travels around the Sun at a speed of 29.8 kilometers per second. At this speed, Earth requires 3.15576×107 seconds to orbit the Sun once. What is the distance from the Earth to the Sun in kilometers? 2. The moon, at an average distance from the Earth of 384,403 km takes 27.32166 days to orbit the Earth. What is the velocity of the moon in kilometers per hour?

On Jan. 2 this year, Earth was 1.471x10^13 cm from the Sun, its closest point to the Sun. The semi-major axis of Earth's orbit around the Sun is 1AU (1.496x10^13 cm. Use this information to determine: A. The eccentricity of Earth's orbit around the Sun. B. The difference between the maximum distance between the Earth and Sun, and the minimum distance between the Earth and the Sun. Convert your answer to AU
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, th
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. ...

A comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.8 × 1010 m (inside the orbit of Mercury), at which point its speed is 9.2 × 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 = ??
