"Periastron" Examples
Perihelion
Usage Examples:
The spacecraft entered the orbit of Mercury just before its perihelion, when the planet is closest to the sun.
Astronomers use the perihelion of a planet's orbit to calculate its semi-major axis and eccentricity.
The perihelion of Mars' orbit is about 1.38 astronomical units (AU) from the sun.
The spacecraft's closest approach to the sun occurred at its perihelion, resulting in a significant increase in solar radiation.
Due to the elliptical shape of its orbit, the perihelion of a comet is often its closest approach to the sun, causing the comet to vaporize and release gas and dust.
