Sedna is a dwarf planet with a highly elliptical orbit. This means its distance from the Sun varies significantly throughout its journey.

Here's a breakdown:

* Average distance: About 863 million kilometers (536 million miles)

* Closest point to the Sun (perihelion): 76 astronomical units (AU)

* Farthest point from the Sun (aphelion): 937 AU

For reference: 1 AU is the average distance between the Earth and the Sun, approximately 150 million kilometers (93 million miles).

So, Sedna can be as close as 76 times the Earth-Sun distance and as far as 937 times that distance!
