All ellipses have two focuses, or "foci". For the Earth's orbit, the Sun is at one focus of the Earth's orbit. There isn't any physical object at the other focus of the Earth's elliptical orbit.

For the Moon, the Earth is at one focus of the Moon's orbit.

What is the period of an ellipse?

1. An ellipse is an oval shape. The orbits of planets are elliptical, i.e. oval shaped. The period of rotation of different planets in their respective elliptical orbits around the sun differs from planet to planet. The period of time that planet Mercury takes to complete its elliptical orbit around the sun is about 88 sidereal days, compared to 365.2564 sidereal days for the Earth. 2. An eclipse is when light from one celestial body is obscured by another celestial body. A solar eclipse is when the sun's light is blocked from the earth by the moon. This eclipse can be total or partial, depending on where on the earth the observer is situated. And the duration of the eclipse varies slightly according to the time of year and respective relative positions of the three celestial bodies involved. A total solar eclipse can be about seven to seven and a half minutes long. Partial eclipses are not as long. Planets other than the earth also experience eclipses as their moons cause shadows on their surfaces. A lunar eclipse occurs when the earth comes between the sun and the moon, blocking the sun's light from the moon and darkening its appearance. A total lunar eclipse can last over an hour, but if we include the partial eclipse time, the overall period/duration of the eclipse can be over three hours.

What is also known as the semimajor axis?

The major axis of an ellipse is its longest diameter, a line that runs through the center and both foci, its ends being at the widest points of the shape.The semi-major axis is one half of the major axis, and thus runs from the centre, through a focus, and to the edge of the ellipse. It represents a "long radius" of the ellipse, and is the "average" distance of an orbiting planet or moon from its parent body.


Are distances between Sun and any planet measured from near edge to near edge or from center to center?

They are centre to centre, but given the relative measures and the fact that the distances are averages over elliptical orbits rather than circular ones, the difference between the two is irrelevant.


Are Johannes Kepler's laws still in effect today?

Kepler discovered many things (most of which i cant name right now), however, he came up with 3 new laws of nature. 1. Planets move in elliptical motions, with the sun at one focus point. 2. A line joining the planet and the sun sweeps out equal area over equal time. 3. The time it takes for a planet to orbit the sun squared, is equal to the average distance between the planet and the sun cubed.

The curved path in which a planet revolves around another body?

Orbit is the term used to describe the curved path that a planet follows as it revolves around another body, such as a star. Orbits are typically elliptical in shape, with the body being orbited located at one of the foci of the ellipse. Orbits are governed by the gravitational pull between the two bodies, with the more massive body at the center of the orbit.


What is a planets orbit?

What shape is the path a planet takes around the sun called?

Ellipse. One of Newton's Laws of Planetary Motion sate that the planets revolve in elliptical orbits with the Sun at one of the two foci.


What do you mean by elliptical trajectory?

An elliptical trajectory is a curved path followed by an object in space, such as a planet or a satellite, where the shape of the path is an ellipse. This trajectory has a point where the object is closest to the body it is orbiting (perigee) and a point where it is farthest away (apogee).

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.
