This applies to any object orbiting the sun, including:

* Planets: Each planet in our solar system has a perihelion point.

* Comets: Comets have very elliptical orbits, so their perihelion can be much closer to the sun than their aphelion (furthest point).

* Asteroids: Asteroids also have perihelion points, though they generally stay within the asteroid belt.

It's important to note that perihelion isn't a fixed point in space, but a specific point in the orbit of an object.
