Each planet has a slightly elliptical orbit and perihelion is the name given to the position in the orbit where it is closest to the Sun.
So the Earth's average distance is 149.6 million km with an eccentricity of 1/60 which means that its distance varies 2.5 million km either side of the average. At perihelion, the distance is 147.1 million km about Jan. 3rd each year.

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 point of the planet is closest too the sun?
They are all exposed to sun light; none of them is closed to the sun. However, from the distance of Neptune the sun is barely discernible from the other stars in the sky, and the dark half of Mercury gets extremely cold because its day is so very long.
When does Earth reach perihelion with the Sun?
Earth reaches perihelion with the Sun around January 2-5 each year. This is the point in its elliptical orbit where it is closest to the Sun.
What point in a planet's orbit is closest to the sun?
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
What is the name of the point on Earth's orbit when Earth is closet to the sun?
The point on Earth's orbit when it is closest to the sun is called perihelion. At perihelion, Earth is approximately 147 million kilometers (91 million miles) away from the sun, compared to its farthest point, aphelion.
How close does perihelion get to then sun?
Perhelion gets close to the sun about January 3rd...
How close does venus get to the sun in perihelion?
107,476,259 km
How close does Mars get the sun in Perihelion?
200145 km
How close does Uranus get to the sun in perihelion?
Uranus gets as close as about 2.75 billion kilometers (1.71 billion miles) to the sun at perihelion, which is the point in its orbit where it is closest to the sun.
How close does mars get to the sun in perihelion?
Mars gets as close as about 206.6 million kilometers to the Sun at perihelion, which is its closest approach. This is in contrast to its average distance from the Sun, which is about 227.9 million kilometers.
What best defines the term perihelion?
Point of a planetary orbit nearest the Sun (per= close, Helios= Sun)
How close is Earth to the Sun at its closest approach?
We call the closest point of approach to the Sun "perihelion". "Peri-" from the Greek for near, and "helion" from the Greek "Helios" or "Sun".At perihelion, the Earth is at a distance of 147,098,074 kilometers or 91,402,506 miles.
What does perihelion ocur?
When an object orbiting the Sun is at its closest distance to the Sun, it is said to be in perihelion.
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
Why is it so cold even though we're in perihelion?
Perihelion is the point in a planet's orbit when it is nearest to the sun. Apehelion is when it's furthest from the sun. We would not be coldest at perihelion.
What is Earth's angular momentum when it is at perihelion in its orbit?
Earth's angular momentum remains constant throughout its orbit around the Sun due to the conservation of angular momentum. The angular momentum at perihelion (closest point to the Sun) is the same as at any other point in its orbit.
How close does Pluto get to the sun in Perihelion?
The distance between the Earth and the Sun at perihelion is 147,098,074 km0.9832898912 AU or 91.4 milion miles).Perihelion is the point of least distance of the elliptical orbit of the Earth from the Sun.
