Pro Tip 1/3Space Phenomenon
A comet is a celestial event, not a regular occurrence, like a star or planet.
The comet’s appearance was an extraordinary event that had astronomers excited.
Pro Tip 2/3Visible Tail
When near the sun, comets often have a visible tail, which distinguishes them from other space bodies.
The comet’s tail stretched across the night sky, clearly visible from Earth.
Pro Tip 3/3Not a Star
Comets are sometimes confused with stars; remember, comets move and have tails.
Although it looked like a star at first, the movement and tail revealed it was a comet.

Ben Carson
American Scientist
I've had experiences in my life that leave no doubt in my mind about the fact that God exists. I'm quite willing to debate people who don't think so because I want them to explain to me how did our solar system get so organized and how is the universe so complex and yet well-organized that we can predict 70 years hence when a comet is coming?
Quote examples
Isaac Newton
English Mathematician
Just as the system of the sun, planets and comets is put in motion by the forces of gravity, and its parts persist in their motions, so the smaller systems of bodies also seem to be set in motion by other forces and their particles to be variously moved in relation to each other and, especially, by the electric force.
Quote examples
Alan Stern
American Scientist
It shouldn't be so difficult to determine what a planet is. When you're watching a science fiction show like 'Star Trek' and they show up at some object in space and turn on the viewfinder, the audience and the people in the show know immediately whether it's a planet or a star or a comet or an asteroid.
Quote examples
Heidi Hammel
American Scientist
Most people have already seen a cosmic collision. If you've seen a shooting star ever, you've seen a cosmic collision, because a shooting star is not a star. It's a tiny dust or pea sized fragment of an asteroid or a comet hitting our atmosphere and burning up as it hits in, as it comes in.

For most of the history of our species we were helpless to understand how nature works. We took every storm, drought, illness and comet personally. We created myths and spirits in an attempt to explain the patterns of nature.
