The orbit of a planet around its star is an ellipse with the star at one focus. The apoapsis of a planet is its greatest distance from the star and the periapsis is it shortest distance. Its mean distance is the length of thr semimajor acid. The apoapsis of a planet is 451 million miles. If the star is 34.4 million miles from the center of the orbit, what is the periapsis? What is the mean distance? Write an equation...
1 points SPreCalc7112.065.MI. My Notes Ask Your Teacher The planets move around the sun in elliptical orbits with the sun at one focus. The point in the orbit at which the planet is closest to the sun is called perihelion, and the point at which it is farthest is called aphelion. These points are the vertices of the orbit. A planet's distance from the sun is 207,000,000 km at perihelion and 249,000,000 km at aphelion. Find an equation for the...

A)Some comets are in highly elongated orbits that come very close to the sun at perihelion. The distance from one such comet to the center of the sun is 6.00×10^9m at perihelion and 3.00×10^12m at aphelion. For this comet's orbit, find the semi-major axis. B) In 2017 astronomers discovered a planet orbiting the star HATS-43. The orbit of the planet around HATS-43 has semi-major axis 7.41×109m, eccentricity 0.173, and period 4.39 days. Find the distance between HATS-43 and the planet...
planet X travels in a circular motion orbit around the Sun. The radius of Planet X is twice that of Earth. The year on Planet X is 540 Earth years. The mass of Planet X is half that of Earth. The mass of the sun is 1.99*10^30 kg. The Earth's orbital distance from the Sun is 1.50*10^11 m.

Pluto's orbit around the Sun is highly elliptical compared to the planets in our Solar System. It has a perihelion distance of 29.7 AU and an aphelion distance of 49.5 AU. a) What is the semi-major axis of Pluto's orbit, in AU? b) What is Pluto's orbital period, in Earth years?
8. A certain star has a mass four times that of our Sun. A planet in orbit around that star has a semimajor axis of 0.45 AU and an eccentricity of 0.32. What is the rate of precession of this planet's "perihelion"?
The orbit of a 1.5 ✕ 1010 kg comet around the Sun is elliptical, with an aphelion distance of 33.0 AU and perihelion distance of 0.850 AU. (Note: 1 AU = one astronomical unit = the average distance from the Sun to the Earth = 1.496 ✕ 1011 m.) (a)What is its orbital eccentricity? (b)What is its period? (Enter your answer in yr.) (c)At aphelion what is the potential energy (in J) of the comet—Sun system?
4. The planet Earth orbits around the Sun and also spins around its own axis. (a) Calculate the angular momentum of Earth in its orbit around the sun. (b) Calculate the angular momentum of Earth spinning on its axis. (c) What is the ratio of the angular momentum of Earth in its orbit to the angular momentum of Earth about its axis?
