Planets don't have circular orbits; all orbits are ellipses. A circle has one center, but an ellipse has two focuses, or "foci". The further apart the foci, the greater the eccentricity, which is a measure of how far off circular the ellipse is.
Venus has the lowest eccentricity, at 0.007. Neptune is next with an eccentricity of 0.011. (Earth's orbit has an eccentricity of 0.017.)
So, Venus has the shortest focus-to-focus distance.
What else can I help you with?
What are EITHER OF two points on the orbit of a planet of greatest or least distance from the central body?
The point on the orbit of a planet that is farthest from the central body is called the aphelion, while the point that is closest is known as perihelion. The distance between the planet and the central body varies depending on its position in the orbit.
Are there at least 15 billion elliptical galaxies in the universe?
There are at least 15 billion elliptical galaxies in the universe.
At what part of an elliptical orbit does a satellite have the greatest speed the least speed?
in the orbit of a planet there is a point called perihelion which is closest point to the sun and aphelion which is furthest from the sun . Moment of a planet in it's elliptical orbit reaches it's maximum in perihelion
Which galaxy is the least common elliptical irregular or spiral galaxy?
I think the least common is elliptical or irregular..
The potential energy of a satellite in an elliptical orbit is?
The total energy of a satellite doesn't change. At its closest approach to the planet, it has the most kinetic energy and the least potential, whereas at its furthest retreat from the planet, it has the least kinetic energy and the most potential. But their sum ... the satellite's total mechanical energy ... is always the same. (It may gain heat energy when the sun is shining directly on it, and lose it when it's in the planet's cold shadow, but neither of those changes affects its orbit.)
What is the closest planet to Jupiter and how far is it?
The distance between the planets depends on their location relative to each other. Sometimes Mars, Sometimes Saturn. The least distance between Jupiter and Saturn is 3.5 AU and The least distance between Jupiter and Mars is 6.7 AU. Hence, Saturn's orbit is slightly closer than Mars' orbit. 1 AU is the distance between the Earth and the Sun. 1 Astronomical Unit = 149 598 000 kilometers
Where is the distance between the continents of Europe and Africa the least?
The least distance is across the Strait of Gibraltar.
Which planet travels the least distance to go around once?
Mercury travels the least distance to go around the Sun once, as it has the shortest orbital path of all the planets in our solar system.
What is the term for the greatest distance between two planets?
Two planets are at their greatest separation when they are on opposite sides of the Sun. When a planet is at its greatest separation from the Earth the planet is said to be at superior conjunction. It cannot be seen until it has separated out from the Sun, which usually takes a few weeks at least.
Why does the Earth have an elliptical orbit around the sun?
I'll assume you mean: "... as opposed to a circular orbit". That is caused by the fact that for a circular orbit, a planet needs a VERY PRECISE SPEED. Change the speed slightly (at a particular point in the orbit), and the orbit immediately becomes elliptical.
What is the safe distance between a photocopying machine and personal workstation?
The safe distance between a photocopying machine and a personal workstation is at least one meter. The distance help in operating the photocopying machine.
In good weather conditions the safe following distance between your vehicle and the one in front of you is at least what distance?
8 seconds
