Earth's Closest Approach to the Sun: Does the Date Change?

[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)

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