Astronomical unit

The astronomical unit (symbol: au, or AU) is a unit of length defined to be exactly equal to.

See 2020 HA10 and Astronomical unit

Aten asteroid

The Aten asteroids are a dynamical group of asteroids whose orbits bring them into proximity with Earth.

See 2020 HA10 and Aten asteroid

Atira asteroids or Apohele asteroids, also known as interior-Earth objects (IEOs), are Near-Earth objects whose orbits are entirely confined within Earth's orbit; that is, their orbit has an aphelion (farthest point from the Sun) smaller than Earth's perihelion (nearest point to the Sun), which is 0.983 astronomical units (AU). 2020 HA10 and Atira asteroid are Atira asteroids.

See 2020 HA10 and Atira asteroid

Degree (angle)

A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle in which one full rotation is 360 degrees.

See 2020 HA10 and Degree (angle)

Ecliptic

The ecliptic or ecliptic plane is the orbital plane of Earth around the Sun.

See 2020 HA10 and Ecliptic

Geometric albedo

In astronomy, the geometric albedo of a celestial body is the ratio of its actual brightness as seen from the light source (i.e. at zero phase angle) to that of an idealized flat, fully reflecting, diffusively scattering (Lambertian) disk with the same cross-section.

See 2020 HA10 and Geometric albedo

Jet Propulsion Laboratory

Jet Propulsion Laboratory (JPL) is a Federally Funded Research and Development Center (FFRDC) in La Cañada Flintridge, California, Crescenta Valley, United States.

See 2020 HA10 and Jet Propulsion Laboratory

Julian day

The Julian day is the continuous count of days since the beginning of the Julian period, and is used primarily by astronomers, and in software for easily calculating elapsed days between two events (e.g. food production date and sell by date).

See 2020 HA10 and Julian day

Minor Planet Center

The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU).

See 2020 HA10 and Minor Planet Center

Mount Lemmon Observatory

Mount Lemmon Observatory (MLO), also known as the Mount Lemmon Infrared Observatory, is an astronomical observatory located on Mount Lemmon in the Santa Catalina Mountains approximately northeast of Tucson, Arizona (US).

See 2020 HA10 and Mount Lemmon Observatory

Mount Lemmon Survey

Mount Lemmon Survey (MLS) is a part of the Catalina Sky Survey with observatory code G96. 2020 HA10 and Mount Lemmon Survey are Discoveries by MLS.

See 2020 HA10 and Mount Lemmon Survey

Near-Earth object

A near-Earth object (NEO) is any small Solar System body orbiting the Sun whose closest approach to the Sun (perihelion) is less than 1.3 times the Earth–Sun distance (astronomical unit, AU).

See 2020 HA10 and Near-Earth object

Orbital eccentricity

In astrodynamics, the orbital eccentricity of an astronomical object is a dimensionless parameter that determines the amount by which its orbit around another body deviates from a perfect circle.

See 2020 HA10 and Orbital eccentricity

Orbital inclination

Orbital inclination measures the tilt of an object's orbit around a celestial body.

See 2020 HA10 and Orbital inclination

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 two most widely separated points of the perimeter.

See 2020 HA10 and Semi-major and semi-minor axes
