What parts of the electromagnetic spectrum are you exposed to in a year?

Where do light years fit on the electromagnetic spectrum?
They don't. A 'light year' isn't anything as romantic as an electromagnetic wave or a gamma ray. A 'light year' is nothing but a lowly unit of length or distance, just like an inch, a mile, or a kilometer. A 'light year' is the distance light travels in a year. That's roughly 5,878,700,000,000 miles. (You can see why it's easier to use 'lights years' than miles to talk about long distances.)

Planets are visible in the night sky because they reflect sunlight. As they do not emit their own light like stars do, they rely on the Sun's light to make them visible to us here on Earth. The brightness and position of planets change as they orbit the Sun, making them observable at different times throughout the year.
