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.
Perhelion gets close to the sun about January 3rd...

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.
The planets closest to the sun are Mercury, Venus, Earth, and Mars.
It varies, 1.66 AU at Aphelion and 1.38 AU at Perihelion.
The fourth planet from the sun is Mars. Aphelion is 249,209,300 km. Perihelion is 206,669,000 km
Point of a planetary orbit nearest the Sun (per= close, Helios= Sun)
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.

When an object orbiting the Sun is at its closest distance to the Sun, it is said to be in perihelion.
Mars has an average distance of about 1.52 astronomical units (AU) from the Sun. However, the range of Mars' distance from the Sun varies due to its elliptical orbit, ranging from about 1.38 AU at its closest approach (perihelion) to about 1.67 AU at its farthest point (aphelion).
