What is the semi major axis of a spacecraft's orbit that has a perihelion distance of 0.1 AU and a aphelion distance of 0.4 AU?
The planet is at minimum and maximum distances when it is at either end of the major axis. In this case the major axis is 0.5 AU so the semimajor axis is 0.25 AU. The eccentricity is found by noting that the Sun is 0.15 AU displaced from the centre, so the eccentricity is 0.15/0.25 or 0.6. The semiminor axis is equal to the semimajor axis times sqrt(1 - e-squared) which in this case is equal to 0.2.
How close does Pluto get to the sun in Perihelion?
The distance between the Earth and the Sun at perihelion is 147,098,074 km0.9832898912 AU or 91.4 milion miles).Perihelion is the point of least distance of the elliptical orbit of the Earth from the Sun.
What is the Position of planet defined by angular distance from last perihelion called?
An anomaly refers to the position of a planet or satellite that is defined by its angular distance from its last perihelion. It is considered an irregularity in the motion of a planet or satellite.
The period of revolution of a planet is most closely related to its what?
Semimajor axis of its orbit, the average of the maximum and minimum distance from the Sun. <<>> That's basically the planet's average distance from the Sun.
What is the distance from the sun to the fourth planet in your solar system?
The fourth planet from the sun is Mars. Aphelion is 249,209,300 km. Perihelion is 206,669,000 km
What's the perihelion distance of Mars?
The difference between the earth's closest approach to its star and its furthest distance away from it depends on how "out of round" or how eccentric is the earth's orbit around the Sun. Simplistically, this eccentricity varies periodically with a period of about 100 thousand years from 0.005 (almost perfectly circular) to about 0.058. The present eccentricity is 0.017 which yields a perihelion of about 91.405 million miles and an apelion of about 94.512 million miles. This varies from year to year.

What word describes the closest distance the planet gets from the sun?
This is called perihelion.

How close does perihelion get to the sun?
Each planet has a slightly elliptical orbit and perihelion is the name given to the position in the orbit where it is closest to the Sun. So the Earth's average distance is 149.6 million km with an eccentricity of 1/60 which means that its distance varies 2.5 million km either side of the average. At perihelion, the distance is 147.1 million km about Jan. 3rd each year.

What is the orbital eccentricity of a planet if the foci distance is 7.6 cm and the major axis is 15.2 cm?

How can you tell which planet has the most circular orbit?
You can look through a list of the planets' orbits to see which one has the smallest eccentricity, and the answer is Venus, 0.006787. But if you are an astronomer wanting to find it out by observing the planets in the sky, you need to have five accurate positions for each planet, spaced out across a good fraction of the orbit, and then you can calculate the 'elements' of the orbit. One of the elements is the eccentricity. The eccentricity and the semimajor axis determine the shape and size of the orbit. Then there is the longitude of perihelion, which sets the orientation of the major axis of the ellipse. Two more are the inclination of the plane of the orbit to the plane of the Earth's orbit, and then the longitude of the ascending node, which defines the line of intersection of the two planes. Finally the longitude at the Epoch and the date of the Epoch are required because they set the starting conditions for the model.
What planet orbits in an oval the most?
The planet with the most elliptical or oval-shaped orbit is Mercury. Its orbit is highly elongated, with a high eccentricity of 0.21. This means that Mercury's distance from the Sun varies significantly throughout its orbit, causing extreme temperature fluctuations on the planet's surface.
