Difference between Earth Similarity Index and Exoplanetology

Earth Similarity Index vs. Exoplanetology

The Earth Similarity Index (ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. Exoplanetology, or exoplanetary science, is an integrated field of astronomical science dedicated to the search and study of exoplanets (extrasolar planets).

Similarities between Earth Similarity Index and Exoplanetology

Earth Similarity Index and Exoplanetology have 13 things in common (in Unionpedia): Albedo, Circumstellar habitable zone, Density, Doppler spectroscopy, Escape velocity, Exoplanet, Greenhouse effect, Mars, Mercury (planet), Methods of detecting exoplanets, Tidal heating, Tidal locking, University of Puerto Rico at Arecibo.

Albedo

Albedo (albedo, meaning "whiteness") is the measure of the diffuse reflection of solar radiation out of the total solar radiation received by an astronomical body (e.g. a planet like Earth).

Circumstellar habitable zone

In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.

Density

The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.

Doppler spectroscopy

Doppler spectroscopy (also known as the radial-velocity method, or colloquially, the wobble method) is an indirect method for finding extrasolar planets and brown dwarfs from radial-velocity measurements via observation of Doppler shifts in the spectrum of the planet's parent star.

Escape velocity

In physics, escape velocity is the minimum speed needed for an object to escape from the gravitational influence of a massive body.

Exoplanet

An exoplanet or extrasolar planet is a planet outside our solar system.

Greenhouse effect

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.

Mars

Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System after Mercury.

Mercury (planet)

Mercury is the smallest and innermost planet in the Solar System.

Methods of detecting exoplanets

Any planet is an extremely faint light source compared to its parent star.

Tidal heating

Tidal heating (also known as tidal working or tidal flexing) occurs through the tidal friction processes: orbital energy is dissipated as heat in either the surface ocean or interior of a planet or satellite.

Tidal locking

Tidal locking (also called gravitational locking or captured rotation) occurs when the long-term interaction between a pair of co-orbiting astronomical bodies drives the rotation rate of at least one of them into the state where there is no more net transfer of angular momentum between this body (e.g. a planet) and its orbit around the second body (e.g. a star); this condition of "no net transfer" must be satisfied over the course of one orbit around the second body.

University of Puerto Rico at Arecibo

The University of Puerto Rico at Arecibo (UPRA or UPR-Arecibo) is a state university located in the city of Arecibo, Puerto Rico, and part of the eleven campuses that compose the University of Puerto Rico system.
