However, it's important to note that Pluto's orbit is highly elliptical, so its distance varies greatly. At its closest point, it's about 2.75 billion miles (4.43 billion kilometers) from the Sun. At its furthest point, it's about 4.6 billion miles (7.4 billion kilometers) away.

Light years are a much larger unit of distance than miles or kilometers. One light-year is the distance light travels in one year, which is about 5.88 trillion miles (9.46 trillion kilometers).

Therefore, Pluto's distance from the Sun is not typically measured in light-years. It's much more practical to use miles or kilometers.
