The earth closest to the sun

[Ulysees]

What time of the year is the Earth closest to the sun?

Does this time vary?

According to wiki, the Earth is closest to the Sun on Jan 3rd. And this time will vary but very slowly (period of about 27000years)

Here's a link showing how the dates of the Perihelion, aphelion, equinoxes and soltices vary over the years.

Of course the biggest jumps in this table are because of leap years.
