Conversation

Did you know that every planet has a point called aphelia?

Really? I had no idea what that was.

Yeah, it's the point in orbit when they're farthest from the sun.

That's interesting! I love learning about space stuff.

Root Explanation

Aphelia is derived from the Greek word "aphelis" (meaning away from the sun). The prefix "a-" (meaning away) combined with "helios" (meaning sun) indicates a position that is farther from the sun. Thus, aphelia refers to the point in an orbit that is farthest from the sun.

Memory Tip

Think of being 'away from' ('a-') the 'sun' ('helios') to remember that aphelia means the point in an orbit that is farthest from the sun.
