pericenter การใช้

• A straight line connecting the pericenter and apocenter is the " line of apsides ".
• It is simply a convenient uniform measure of how far around its orbit a body has progressed since pericenter.
• It is equal to 0 when the body is at the pericenter, radians ( 180?) at the apocenter, and 2 radians ( 360?) after one complete revolution.
• Astronomers commonly express the timing of perihelion relative to the vernal equinox not in terms of days and hours, but rather as an angle of orbital displacement, the so-called longitude of the pericenter.
• :: Faster speed and greater gravitational potential both act to create more slowing, so the closest approach in an elliptical orbit ( pericenter ) will have more time dilation than the furthest distance ( apocenter ) . talk ) 10 : 22, 4 November 2014 ( UTC)
• "Tina " is the namesake of the Tina family a group of 17 89 asteroids that form a small, well-defined asteroid family, which share similar ?6 secular resonance, i . e ., the longitudes of pericenter of the asteroids follow the longitudes of pericenter of Saturn by 180 degrees.

• "' Source 2 "'( abbreviated "'S2 "'), also known as "'S0 2 "', is a star that is located close to the radio source Sagittarius A *, orbiting it with an orbital period of 15.56 ?0.35 years and a pericenter distance of 17 AU )  an orbit with a period only about 30 % longer than that of Jupiter around the Sun, but coming no closer than about four times the distance of Neptune from the Sun.
