A light year is a measurement of distance, not time. It is the distance that light travels in a year. Light travels at about 186,000 miles per second, or 300,000 kilometres per second. There are over 31.5 million seconds in a year. So 3230 light years is a massive distance.

Gemini, Leo, and Canis Major are all examples of constellations in the night sky. Constellations are groups of stars that form recognizable patterns as seen from Earth. They have been used for navigation, storytelling, and scientific study for centuries.

Well, darling, an air temperature of 95 degrees Celsius is typically found in the thermosphere. That's the hot spot where temperatures can soar due to its proximity to the sun. Just make sure to pack some sunscreen if you're planning a visit up there!

Oh, dude, those dark seas on the moon are called "maria." Yeah, like Maria, but with an extra "i."

So, if you're planning a lunar beach vacation, you might want to rethink that.

On a sphere, parallel lines CAN meet.

Offgassing occurs when comets, meteors, meteorites etc. are heated by an outside force (such as the sun or the atmosphere of a planet.)
This heating causes the frozen gasses and particles of the object to vaporize, creating the clouds of gas and particles that surround comets and make them visible.

1. 1. The partial or complete obscuring, relative to a designated observer, of one celestial body by another.
   2. The period of time during which such an obscuration occurs.

One year is the time that it takes for the Earth to complete one orbit around the Sun, approximately 365.24 days. The ".24" days part is the reason for Leap Years; this keeps the calendar in synchronization with the actual movement of the Earth around the Sun.

We are at the beginning of the third millennium of the common era (or AD, to those who prefer it).
