The eccentricity of a planet's orbit describes?
diviation in shape to circle
What two measurable properties directly tell us the size and shape of a planet's orbit?
The semi-major axis (size) and the eccentricity (shape).
Shape of earth and moons orbit?
All orbits are elliptical. Some, like Earth's are ALMOST circles, but every orbit has at least a little bit of eccentricity.
Does mars orbit the sun in a circle shape?
No. A circle is an unstable shape for an object orbiting another. An orbit is between slightly and very elliptical (egg-shaped). If an object is placed in a circular orbit, the orbit will quickly deteriorate to an elliptical orbit. Added: Mar's elliptical eccentricity is rather above average for a planetary orbit. Not quite as large as Mercury, but large enough.
Is the shape of the orbit of each planet is a circle true?
No, all the planets have orbits that are technically ellipses with low eccentricity. Apart from Mercury all the other seven planets have orbits that are very nearly circular, but the Sun is offfset from the centre of the circle by a different amount for each planet depending on the eccentricity of the orbit.
What happens to the shape of planet's orbit as its eccentricity increases?
The orbit becomes more eccentric until the orbit becomes almost a strait line.

What orbit shape is Mercury?
Mercury's orbit, like all planet's, is elliptical.The eccentricity of Mercury's orbit is 0.206
When was the Eccentricity?
100,000 and 400,000 years, caused by changes in the shape of earth's orbit around the sun.

What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
What is the actual shape of the Earths orbit around the Sun?
The actual shape of the earth's orbit around the sun is horrendously complicated. Partly because the earth does not orbit the sun and also because the orbit is influenced by the the gravitational attraction of the other planets. The earth does not orbit the sun: the centre of mass of the earth-sun system is at one of the foci of an ellipse whose eccentricity is 0.0167. The eccentricity varies from 0.0034 to 0.058.
What shape is the earth orbiting?
The shape of Earth's orbit becomes more or less oval (eccentricity), Earth wobbles as it spins (precession), and Earth's axis changes too (tilt).
Does mars orbit the sun in a circle shape?

If an object is placed in a circular orbit, the orbit will quickly deteriorate to an elliptical orbit. Added: Mar's elliptical eccentricity is rather above average for a planetary orbit.

The ellipse with less eccentric is smaller or larger than an ellipse with more eccentric?
Eccentricity does not refer to the [size] of the ellipse. It refers to the [shape].An ellipse with [zero] eccentricity is a [circle].As the eccentricity increases, the ellipse becomes less circular,and more 'squashed', like an egg or a football.
