A comet has a period of 72.3 years and moves in an elliptical orbit in which its perihelion (closest approach to the Sun) is 0.650 AU. Find the semimajor axis of the comet and an estimate of the comet's maximum distance from the Sun, both in astronomical units. (a.) the semimajor axis of the comet (in AU). (b.) an estimate of the comet's maximum distance (in AU) from the Sun.
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. ...
Kepler’s Third Law indicates that the Period (P) of an orbit is related to the semi-major axis (a) of the orbit with: P 2 = ka3 . Kepler noticed that the value of the constant k changes when we observe systems with different central objects. This means that the orbits of all of the planets in the Solar System have the same value for k, but that value is different for the Moon because all of the planets orbit the...
