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.
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.
The planets closest to the sun are Mercury, Venus, Earth, and Mars.
At perihelion Venus is about:107,476,259 km (66,782,651.2 miles) (0.71843270 AU)
Venus can get closer to the Earth and it can also get further away (when it is on the opposite side of the Sun in it's orbit). At closest approach Venus is about 41 million kilometers. At perihelion (point in orbit closest to the Sun) Earth is 147 million km from the Sun.
Point of a planetary orbit nearest the Sun (per= close, Helios= 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.
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.
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.
When an object orbiting the Sun is at its closest distance to the Sun, it is said to be in perihelion.
