An apoapsis is the point of a body's elliptical orbit around the system's centre of mass where the distance between the body and the centre of mass is at its maximum.
The farthest point in an orbit from the parent object is called apoapsis.
Periapsis is the point in an orbit closest to the body being orbited, while apoapsis is the point farthest from the body being orbited. These terms are used in orbital mechanics to describe the closest and farthest points of an object's orbit around another object in space.
The points farthest from a planet are called apoapsis, while the points nearest to a planet are called periapsis. Apoapsis is the farthest point in an orbit, and periapsis is the closest point in an orbit.
Its apparent diameter is about half a degree, or 30 minutes. It actually varies a bit, depending on whether the Earth is in periapsis or in apoapsis.
That's when the Moon is farthest from Earth - in other words, at apoapsis.
The point in a body's orbit when it is farthest from its primary is apoapsis. For the specific case of a body orbiting Earth, you can also use the term apogee.
An apocentre is another name for an apoapsis, the point of a body's elliptical orbit around its system's centre of mass where the distance between the body and the centre of mass is at its maximum.
That is called apapsis or apoapsis. For orbits that are specifically around the Sun, the term aphelion is also used.
Yes, and at other times it is closer.When it is closest, the planet orbiting the Sun (or any other object, orbiting anything else) is said to be in periapsis; when it is furthest away, it is in apapsis or apoapsis.
14 moons as of 2013,starting with nareid,apoapsis,periapsis,proteus,naiad,thalassay,despina,galatia,larissa, triton being the largest , and the new smallest s 2004n/1.
The difference is hard to notice without special instruments. The distance to the Moon at periapsis is about 363,000 km; at apoapsis the distance is about 405,000 km - a difference of about 12%. That will also be the apparent difference in size.
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
