Asteroid Orbits: Paths Around the Sun

Eccentricity measures the deviation of an orbit from a perfect circle, with values ranging from 0 (circular) to 1 (parabolic).

Kepler's Third Law, also known as the Law of Harmonies, describes the relationship between an asteroid's orbital period and its distance from the Sun.

Perihelion is the point in an asteroid's orbit where it is closest to the Sun, while aphelion is the point where it is farthest from the Sun.

Juno has an eccentricity of 0.256, making it the most eccentric asteroid among the four largest asteroids in the asteroid belt.

The Flora family is known for its high inclination and eccentric orbits, with members having inclinations up to 25 degrees and eccentricities up to 0.4.

Inclination measures the angle between an asteroid's orbital plane and the ecliptic, the plane of Earth's orbit around the Sun.

Ceres has a semi-major axis of 2.77 AU, making it the asteroid with the largest average distance from the Sun.

Aphelion is the point in an asteroid's orbit where it is farthest from the Sun, while perihelion is the point where it is closest to the Sun.

The Vesta family is known for its low inclination and nearly circular orbits, with members having inclinations typically less than 10 degrees and eccentricities less than 0.1.

Semi-major axis is the average distance of an asteroid from the Sun, measured in astronomical units (AU).

Vesta has an inclination of only 7.3 degrees, making it the asteroid with the lowest inclination relative to the ecliptic.

Ascending node is the point in an asteroid's orbit where it crosses the ecliptic from south to north, while descending node is the point where it crosses from north to south.

The Eos family is known for its high eccentricity and moderate inclination, with members having eccentricities up to 0.3 and inclinations up to 20 degrees.

Descending node is the point in an asteroid's orbit where it crosses the ecliptic from north to south, while ascending node is the point where it crosses from south to north.
