Halley's Comet has a perihelion distance of 0.6 AU and an
orbital period of 76 years. What is its aphelion distance from
the Sun?
A comet has a period of 76.3 years and moves in an ellipticalorbit in which its perihelion (closest approach to the Sun)is 0.610 AU. Find (a) the semimajor axis of the comet and(b) an estimate of the comet’s maximum distance from theSun, both in astronomical units.
(to two decimal places): (what is ‘h’?)
Eccentricity of earth orbit is 0.0167
µ(sun) = 1.32712E+11 km^3/s^
semimajor axis of Earth orbit = 1.49598E+08
need to figure out what ‘h’ is.
a) Calculate the speed of the earth around the sun at aphelion? (29.29 KM/S)
b) At perihelion? (30.29 KM/S)

- Kepler’s third law says that the orbital period (in years) is proportional to the square root of the cube of the mean distance (in AU) from the Sun (Pa1.5) . For mean distances from 0.1 to 32 AU, calculate and plot a curve showing the expected Keplerian period. For each planet in our solar system, look up the mean distance from the Sun in AU and the orbital period in years and overplot these data on the theoretical Keplerian curve.arrow_forwardWhat is the average distance from the Sun (in astronomical units) of a planet with an orbital period of 45.66 years?arrow_forwardA comet has a period of 76.3 years and moves in an ellipticalorbit in which its perihelion (closest approach to the Sun)is 0.610 AU.
