The distance to the Sun at perihelion varies depending on the object in question.

Here are some examples:

* Earth: 147.1 million kilometers (91.4 million miles)

* Mercury: 46 million kilometers (29 million miles)

* Venus: 107.5 million kilometers (66.8 million miles)

* Mars: 206.7 million kilometers (128.4 million miles)

* Comet Halley: 87.7 million kilometers (54.5 million miles)

Perihelion is the point in an object's orbit around the Sun where it is closest to the Sun.
