PERIHERM Meaning and
Definition
-
Periherm is a term derived from the Greek words "peri" meaning around or surrounding, and "herma" meaning boundary or limit. It is a concept often used in astronomy and planetary science to describe the position of a celestial body, such as a planet or moon, in its orbit when it comes closest to its central body or star.
Specifically, periherm refers to the moment or point in an orbit where a celestial body is at its closest distance to the object it is orbiting. This term is most commonly used in relation to objects orbiting the Sun, like planets or asteroids. For example, in the case of Earth, the periherm occurs when our planet is at its closest point to the Sun during its elliptical orbit.
The distances between the celestial body and the central body can vary depending on the specific orbit and the eccentricity of the orbit. The periherm is also closely related to the term "perihelion," which is the equivalent concept but specifically refers to the closest point to the Sun in a planet's orbit.
In summary, periherm is a term used in astronomy to describe the point in an orbit where a celestial body is closest to the object it is orbiting, such as the Sun for planets. It is a fundamental concept in understanding the dynamics of celestial objects and their movements within the solar system.
