Apsis
An apsis (ἁψίς; plural apsides, Greek: ἁψῖδες) is an extreme point in the orbit of an object.

Asteroid
Asteroids are minor planets, especially those of the inner Solar System.

Asteroid belt
The asteroid belt is the circumstellar disc in the Solar System located roughly between the orbits of the planets Mars and Jupiter.
New!!: Hilda asteroid and Asteroid belt · See more »
Asteroid family
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination.
New!!: Hilda asteroid and Asteroid family · See more »
Astronomical unit
The astronomical unit (symbol: au, ua, or AU) is a unit of length, roughly the distance from Earth to the Sun.

C-type asteroid
C-type (carbonaceous) asteroids are the most common variety, forming around 75% of known asteroids.
New!!: Hilda asteroid and C-type asteroid · See more »
Comet
A comet is an icy small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing.
New!!: Hilda asteroid and Comet · See more »
Conjunction (astronomy)
In astronomy, a conjunction occurs when two astronomical objects or spacecraft have either the same right ascension or the same ecliptic longitude, usually as observed from Earth.

D-type asteroid
D-type asteroids have a very low albedo and a featureless reddish spectrum.

Ecliptic
The ecliptic is the circular path on the celestial sphere that the Sun follows over the course of a year; it is the basis of the ecliptic coordinate system.
New!!: Hilda asteroid and Ecliptic · See more »
Equilateral triangle
In geometry, an equilateral triangle is a triangle in which all three sides are equal.
New!!: Hilda asteroid and Equilateral triangle · See more »
Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
New!!: Hilda asteroid and Jupiter · See more »
Jupiter trojan
The Jupiter trojans, commonly called Trojan asteroids or just Trojans, are a large group of asteroids that share the planet Jupiter's orbit around the Sun.

Kepler's laws of planetary motion
In astronomy, Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun.
New!!: Hilda asteroid and Kepler's laws of planetary motion · See more »
Lagrangian point
In celestial mechanics, the Lagrangian points (also Lagrange points, L-points, or libration points) are positions in an orbital configuration of two large bodies, wherein a small object, affected only by the gravitational forces from the two larger objects, will maintain its position relative to them.

List of minor-planet groups
A minor-planet group is a population of minor planets that share broadly similar orbits.

Monthly Notices of the Royal Astronomical Society
Monthly Notices of the Royal Astronomical Society (MNRAS) is a peer-reviewed scientific journal covering research in astronomy and astrophysics.

Near-Earth object
A near-Earth object (NEO) is any small Solar System body whose orbit can bring it into proximity with Earth.
New!!: Hilda asteroid and Near-Earth object · See more »
Orbit
In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet.
New!!: Hilda asteroid and Orbit · See more »
Orbital eccentricity
The orbital eccentricity of an astronomical object is a parameter that determines the amount by which its orbit around another body deviates from a perfect circle.
New!!: Hilda asteroid and Orbital eccentricity · See more »
Orbital inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body.
New!!: Hilda asteroid and Orbital inclination · See more »
Orbital period
The orbital period is the time a given astronomical object takes to complete one orbit around another object, and applies in astronomy usually to planets or asteroids orbiting the Sun, moons orbiting planets, exoplanets orbiting other stars, or binary stars.
New!!: Hilda asteroid and Orbital period · See more »
Orbital resonance
In celestial mechanics, an orbital resonance occurs when orbiting bodies exert a regular, periodic gravitational influence on each other, usually because their orbital periods are related by a ratio of small integers.
New!!: Hilda asteroid and Orbital resonance · See more »
P-type asteroid
P-type asteroids have low albedo and a featureless reddish spectrum.
New!!: Hilda asteroid and P-type asteroid · See more »
Perihelion and aphelion
The perihelion of any orbit of a celestial body about the Sun is the point where the body comes nearest to the Sun.
New!!: Hilda asteroid and Perihelion and aphelion · See more »
Planet
A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.
New!!: Hilda asteroid and Planet · See more »
Retrograde and prograde motion
Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is the central object (right figure).
New!!: Hilda asteroid and Retrograde and prograde motion · See more »
Semi-major and semi-minor axes
In geometry, the major axis of an ellipse is its longest diameter: a line segment that runs through the center and both foci, with ends at the widest points of the perimeter.

Sun
The Sun is the star at the center of the Solar System.

Trojan (astronomy)
In astronomy, a trojan is a minor planet or moon that shares the orbit of a planet or larger moon, wherein the trojan remains in the same, stable position relative to the larger object.
