In early January, during winter in the northern hemisphere, summer in the south, earth is at perihelion, closest to the sun. This is the opposite of aphelion, which is when the orbit of the Earth is farthest from the sun.

The Sun therefore cannot have a perihelion, unless you define it against the galactic centre and that is another question entirely.

∙ 14y agoThe point in Earth's orbit where it is furthest from the sun is called the Aphelion and occurs in the first week of July. In 2009 the aphelion was at 2 am on July 4th ; in 2010 it will be at 11 am on July 6th

Aphelion is the point of greatest distance of the elliptical orbit of the Earth from the Sun.

The angle of the Earth's axis relative to the Sun determines the seasons, while the variance of the distance from the Sun has less effect. This is why the seasons are opposite in the Northern and Southern hemispheres. When the north pole is angled towards the Sun the south pole is angled away and vice versa.

Note that the Earth's Anomalistic year, the year with respect to the Earth's orbital apsides (aphelion and perihelion), is not the same length as the tropical year we normally use. It is 365.259 635 864 days long, rather than 365.242 189 67.

in the evening of July 3 this year. (0200 GMT 7-4-09).

∙ 11y agoThat depends not so much on aphelion vs. perihelion, but whether Venus and Earth are on the same side or on opposite sides of the Sun.

Precession of earth's axis causes the date at which perihelion of earth's orbit occur to slowly change?
No.
When sun is nearest to earth it is called?
Perihelion.
What is called when earth is closest to the sun?
Perihelion is when the Earth is closest to the sun.
What is Earth's angular momentum when it is at perihelion in its orbit?
The point at which Earth is closest to the the Sun is called perihelion. Even though Earth is close to the Sun then, the Northern hemisphere experiences winter then. This is because the Northern Hemisphere is tilted away from the Sun at perihelion.
Do perihelion and the December solstice happen on earth at the same moment?
no
What was the date of the last time earth was at perihelion?
January 3, 2010 was the date of the "most recent" perihelion. Hopefully, not the "last" one.
What was the date the last time earth was at perihelion?
Well the date it was the last time was acually March,22,1470
What was the date the last time earth was perihelion?
I think the most recent was actually January 4, 2001 at 5am eastern standard time.
Precession of earth's axis causes the date at which perihelion of earth's orbit occur to slowly change?
No.
What is special about January?
Earth reaches its perihelion on January 3rd. On this date it is at its closest to the Sun.
What is the earth's greatest velocity?
perihelion
The perihelion is during the month of?
Earth reaches the point in its orbit called 'perihelion' early in January.
Which date Earth is at shortest distance from the sun?
At the moment (this date changes over long periods due to precession and Milankovitch cycles), Earth's perihelion (closest point to the sun in an elliptical orbit) occurs around January 3rd, and the aphelion (furthest point from the sun in an elliptical orbit) around July 4th. The changing Earth-Sun distance results in an increase of about 6.9% in solar energy reaching the Earth at perihelion relative to aphelion.
What direction is the perihelion on the Earth pointing?
TO THE NORTH
When sun is nearest to earth it is called?
Perihelion.
When sun is nearest to the earth is called?
Perihelion
When is earth's orbital velocity the fastest?
perihelion
