Most orbits are elliptical; all NATURAL orbits are. There are two foci, or focuses, to an ellipse. The distance between the foci determines how eccentric, or non-circular, they are.
If the two foci are in the same place, then the ellipse becomes a circle. So a circular orbit would have only one focus.
What else can I help you with?
What planets has the least distance between the two foci of its elliptical orbit?
Pluto Thanks for the answer! Unfortunately I meant to restrict the question to the 5 planets visible with the unaided-eye. Mercury, Venus, Mar, Jupiter & Saturn (excluding Earth). My mistake. Then again, perhaps its the planet furthest from the sun would have the greatest deviance from a perfect circular orbit. In that case, of the classical 5, it might be Saturn.
Is the sun located in one of the foci of the earths orbit?
No, the sun is located at one of the two foci of Earth's elliptical orbit, not in the exact center.
Which object is located at one foci of the elliptical orbit of Mars?
probably the sun since one of earths eliptical foci is the sun
What is the shape of the path of a planet or asteroid around the sun called?
The path itself is called its orbit. The shape is an ellipse, with the sun sitting at one of the foci.
Which planet has the perfect circular orbit?
No planet has a perfectly circular orbit, though Venus has the least orbital eccentricity of any planet in our solar system.
Are the orbit of planets circular How may their path be best described?
The orbits of planets are actually elliptical, not perfectly circular. An ellipse is a stretched-out circle. The shape of a planet's orbit can be described as an ellipse with the Sun at one of the two foci.
What planet has the least distance between the two Foci of its elliptical orbit?
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.

Is the sun located in one of the foci of the earths orbit?
No, the sun is located at one of the two foci of Earth's elliptical orbit, not in the exact center.
What happen as foci of an ellipse get closer together?
The ellipse will become more circular until it becomes a circle when the two foci coincide.
Which has the almost circular orbit?
Venus has the almost circular orbit.
Which object is located at one foci of the elliptical orbit of Mars?
probably the sun since one of earths eliptical foci is the sun
Is it true or false that the shape of the orbit of each planet is a circle?
False. The shape of the orbit of each planet is an ellipse, not a perfect circle. This is described by Kepler's First Law of Planetary Motion, which states that planets move in elliptical orbits with the Sun at one of the foci. While some orbits may appear nearly circular, they are not perfectly circular.
What is the shape of the path of a planet or asteroid around the sun called?
The path itself is called its orbit. The shape is an ellipse, with the sun sitting at one of the foci.
What is the word for a circular path?
circuitous path orbit
Which planet has the perfect circular orbit?
No planet has a perfectly circular orbit, though Venus has the least orbital eccentricity of any planet in our solar system.
We know that Earth's orbit is a because the distance between Earth and the Sun changes during the year?
Earth's orbit is not perfectly circular, but rather an elliptical shape, with the Sun at one of the foci. This causes the distance between Earth and the Sun to vary slightly throughout the year, with the closest point being perihelion and the farthest point being aphelion.
