Apparent magnitude
Apparent magnitude is a measure of the brightness of a star or other astronomical object.
See TOI-4138 b and Apparent magnitude
Astronomical transit
In astronomy, a transit (or astronomical transit) is the passage of a celestial body directly between a larger body and the observer.
See TOI-4138 b and Astronomical transit
Circumpolar star
A circumpolar star is a star that, as viewed from a given latitude on Earth, never sets below the horizon due to its apparent proximity to one of the celestial poles.
See TOI-4138 b and Circumpolar star
Day
A day is the time period of a full rotation of the Earth with respect to the Sun.
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.
See TOI-4138 b and Doppler spectroscopy
Effective temperature
The effective temperature of a body such as a star or planet is the temperature of a black body that would emit the same total amount of electromagnetic radiation.
See TOI-4138 b and Effective temperature
Exoplanet
An exoplanet or extrasolar planet is a planet outside the Solar System.
Hot Jupiter
Hot Jupiters (sometimes called hot Saturns) are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital periods (. TOI-4138 b and hot Jupiter are hot Jupiters.
See TOI-4138 b and Hot Jupiter
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).
Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
Light-year
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly 9,460,730,472,580.8 km (Scientific notation: 9.4607304725808 × 1012 km), which is approximately 5.88 trillion mi.
Mercury (planet)
Mercury is the first planet from the Sun and the smallest in the Solar System.
See TOI-4138 b and Mercury (planet)
Orbital inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body.
See TOI-4138 b and Orbital inclination
Orbital period
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object.
See TOI-4138 b and Orbital period
Solar mass
The solar mass is a standard unit of mass in astronomy, equal to approximately.
Subgiant
A subgiant is a star that is brighter than a normal main-sequence star of the same spectral class, but not as bright as giant stars.
Sun
The Sun is the star at the center of the Solar System.
Transiting Exoplanet Survey Satellite
Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorer program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission.
See TOI-4138 b and Transiting Exoplanet Survey Satellite
Ursa Minor
Ursa Minor (Latin: 'Lesser Bear', contrasting with Ursa Major), also known as the Little Bear, is a constellation located in the far northern sky.
