Perihelion is the point in an object's orbit around the sun where it is closest to the sun.
Comes from greek peri- =near
Anahelion is the opposite--the point in an object's orbit around the sun where it is farthest from the sun.
Comes from greek ap--=away
The -helio part of each of these specifies that the object is orbiting around the sun. There are other words for orbiting different things.

How far away is Mars from the Sun in AU?
It varies, 1.66 AU at Aphelion and 1.38 AU at Perihelion.
When is Jupiter at its closest to the Earth when it is at what elongation position?
Jupiter is closest to Earth when Jupiter is at perihelion, and Earth is at aphelion. Perihelion is when a planet is closest to the sun. Aphelion is when the planet is farthest from the sun.
What is the term for when a planet is at the point of its orbit nearest the sun?
The closest point to the Sun in a planet's orbit is called perihelion. The furthest point is called aphelion. Phil
What is the distance in Au between the sun and mercury which is km from the sun?
At its furthest (aphelion) 0.467 AU and at its nearest (perihelion) 0.307 AU.
What is the distance between the Sun and Earth called?
The nearest distance is called the perihelion and the furthest distance is called the aphelion (there is about 5 million km difference). The mean distance is called one astronomical unit.
Is Pluto perihelion or aphelion?
aphelion
Is the northern hemisphere summer during aphelion or perihelion?
The Aphelion.
Is 147 000 000 km aphelion or perihelion?
Perihelion.
Does a planet travel fastest at aphelion or perihelion?
Neptune is located at aphelion in its orbit. It is the furthest from the Sun while it is in its orbit.
Does earth move faster in its orbit near perihelion (January) or near aphelion (July)?
In elliptical orbits, all bodies travel faster when nearest the "primary"; in this case, the Sun. Since the Earth's orbit isn't very eccentric (meaning that it is almost but not quite circular) the difference between perihelion velocity and aphelion velocity isn't very great.
When is Jupiter at its closest to the Earth when it is at what elongation position?
Jupiter is closest to Earth when Jupiter is at perihelion, and Earth is at aphelion. Perihelion is when a planet is closest to the sun. Aphelion is when the planet is farthest from the sun.
How far away is Mars from the Sun in AU?
It varies, 1.66 AU at Aphelion and 1.38 AU at Perihelion.
What is the term for when a planet is at the point of its orbit nearest the sun?

What is it called when your closest to the sun?
Perihelion - Aphelion is when the Earth is furthest from the Sun.
What is the name of the point in space where an object is closest to the sun?
That is perihelion. Furthest away is aphelion, pronounced ap-helion. For each planet, perihelion and aphelion are at opposite ends of the major axis of the elliptical orbit.
What is the distance in Au between the sun and mercury which is km from the sun?
At its furthest (aphelion) 0.467 AU and at its nearest (perihelion) 0.307 AU.
In Ontario is the sun actually closer to the earth in winter?
Yes, it actually is. The difference between earth's closest approach to the sun (perihelion) and its farthest approach to the sun (aphelion) is more than 3.1 million miles.
