Pluto is located at an average distance of about 39.5 astronomical units (AU) from the Earth. One astronomical unit is the average distance from the Earth to the Sun, which is approximately 93 million miles or 150 million kilometers.
To convert this distance into light years, we need to understand that one light year is the distance that light travels in one year, which is about 5.88 trillion miles or 9.46 trillion kilometers. Given that, the distance from Earth to Pluto in light years is roughly 0.000628 light years.
This means that light from Pluto takes about 5.5 hours to reach Earth. Despite being relatively close in astronomical terms, Pluto is still incredibly far away when compared to distances we are familiar with on Earth.
