How many foci in circular orbit?
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.
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
How are foci related to eccentricity?
The eccentricity of an ellipse is a number related to how "egg-shaped" it is ... the difference between the distance through the fat part and the distance through the skinny part. That's also related to the distance between the 'foci' (focuses) of the ellipse. The farther apart the foci are, the higher the eccentricity is, and the flatter the ellipse is. Comets have very eccentric orbits. When the two foci are at the same point, the eccentricity is zero, all of the diameters of the ellipse have the same length, and the ellipse is a circle. All of the planets have orbits with small eccentricities.
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.
How far is the sun away from us?
Approximately 93,000,000 miles. This distance varies because the Earth orbits the Sun in an ellipse, with the Sun at one of the foci of the ellipse. NB The Sun is NOT at the centre of ellipse. NNB The other foci of the ellipse may be thought of as a 'blind focus'. NNNB 'Foci' is the noun plural of 'the focus' . 'Focuses' is a verb.
What is the focus of a hyperbola?
The foci (plural of focus, pronounced foh-sigh) are the two points that define a hyperbola: the figure is defined as the set of all points that is a fixed difference of distances from the two points, or foci.
How do you say plural foci?
Foci is the plural form of the singular noun focus.
What is foci?
Foci, (the plural of focus), are a pair of points used in determining conic sections. They always fall on the major axis of symmetry of a conic. For example, in a circle, there is only one focus, the centerpoint. Every distance from the focus to any other point on the circle will be the same. In a parabola, the distance from any point of the parabola to the focus equals the distance from the centerpoint to the directrix. In a hyperbola, the difference of the distances between a point on the hyperbola and the focus points will be constant, and in an ellipse, the sum of the distances from any point on the ellipse to one of the foci is constant.
What is the difference between a circle and an ellipse?
-- the eccentricity or -- the distance between the foci or -- the ratio of the major and minor axes
What is the name of the two centers of an ellipse?
The two centers of an ellipse are called the foci (singular: focus). The foci are two distinct points along the major axis of the ellipse, and the sum of the distances from any point on the ellipse to these two foci is constant. Additionally, the center of the ellipse, which is the midpoint between the foci, is another important point but is distinct from the foci themselves.
A is a point that helps to define an ellipse?
focus
Which word does not belong focus foca focuses foci?
The word foca is not a form of the word focus, which has plurals focuses or foci. It is used as a proper noun or acronym.
Every ellipse has two of what?
Foci (correct plural of focus)
What is the english plural word for the word focus?

What is a cystic foci in a kidney?
A cystic foci, or cystic focus, is when an ultrasound identifies a finding that is cystic-like. It mean there's a tiny collection of fluid wherever the cystic focus was found.

How does distance between foci affect eccentricity?
As the distance between foci increases the eccentricity increases, or the reverse relationship.
