I'm not trying to calculate the perihelion of Jupiter or do 3D renderings of the National Cathedral.
The planet consequently receives nearly three times as much light and heat in perihelion as in aphelion.
In the orbit of a planet, means the line joining its aphelion and perihelion.
That's why we have our golf season while Mars is in his perihelion.
The denser portion of the meteoric stream was then approaching its perihelion.
It entirely escaped observation, both in Europe and America, during its perihelion passage in 1857.
The perihelion passage of 1456 was, until recently, the earliest known.
In like manner, if the periodic time is 3325 years, only a small portion of the orbit near the perihelion fulfills it.
The time of a complete revolution of the perihelion is computed at 108,000 years.
Newcomb finds the anomalous motion of the perihelion to be even larger (43′ instead of 38′) than Leverrier made it.
The point at which an orbiting object, such as a planet or a comet, is closest to the Sun. Compare aphelion, perigee.
