What are the planets has the most elliptical and tilted orbit?

None of the planets orbit the sun perfectly in a circle, there is a degree of deviation from this perfect circle called eccentricity. The higher the eccentricity (more more the eccentric the orbit is) the further away from this perfect circle the orbit is. The planet that deviates most from a perfect circle, having the highest eccentricity, is Neptune. Neptune also has the highest axial tilt, tilted over onto its side as it orbits the sun.


What is the approximate compression of the earths orbit around the sun?

The Earth's orbit is almost circular. Technically, the "eccentricity" of the orbit is about 0.0167.


Which planets orbits are almost round?

Venus has the orbit closest to a circular orbit. Neptune's is not too bad also. Look for low' eccentricity' rating, the closer to zero the more circular.

What is Eccentricity?

Eccentric means, literally, "off center". The term originated with astronomy. Later, it came to be used in mechanics, to describe a wheel or gear which rotates about an axle which is not at its center. (To understand how eccentric motion can be useful. See animation of a automobile cam in related link below.) Around 1620, the term was first applied figuratively, to describe a thing which was odd or unusual. Around 1832, it began to be used to describe a person with unusual ideas or behavior.Eccentric means deviating from the recognized or customary character or practice.With regard to people, eccentric means behaving in odd, unusual ways without the implication of mental illness.

Which equation should be used to find the eccentricity of the earths orbit?

Eccentricity is the measure of how much the conic section diverges into its circle form. One of the formulas for eccentricity is e=c/a this formula can be used to get the eccentricity of the ellipse.

What are some sentences for eccentricity?

"The old man's eccentricity was worrying." "Eccentricity is for the rich - the poor man is simply mad." "I am conducting a study of perceptions of eccentricity in different cultural groups." "Eccentricity should not be considered to be a negative aspect of personality, but rather a fascinating idiosyncrasy."


What orbit has the eccentricity that is closest to 0?

Circular orbit has an eccentricity of 0 as it is perfectly round.


Which planet has an orbital eccentricity most like the orbital eccentricity of the earth?

The Earths orbit is fairly un-eccentric when compared to the other planets, with only Neptune and Venus having more regular (less eccentric) orbits. The eccentricity of earths orbit is 0.0167, the closest to this is Neptune's, with a value of 0.00859


What will happen to the eccentricity of an ellipse as the distance between the foci increases?

the eccentricity will increase.


Is the earths eccentricity more or less eccentricity than a circle?

The Earth's eccentricity is less than that of a perfect circle. Earth's orbit around the Sun is an ellipse with an eccentricity of about 0.0167, which means it is nearly circular.
