A gigantic, green light is the comet C2017S3.
It was made its closest approach to Earth on August 7. Space.com says that this is likely the first time the comet has ever come into the inner solar system.
The comet was discovered on December 23, 2017, that was officially named comet C2017S3 by the PanSTARRS telescopes in Haleakala, Hawaii. According to space.com “the flying, green space rock has already given skywatchers a couple of surprising treats, with bright bursts exploding from its surface twice in close succession — first on June 30, and then again about two weeks later, Sky and Telescope reported. As Hulk himself might say, “Comet flash!”
Some reports have been said that the green comet will cause some sort of apocalyptic upheaval on Earth. But do not worry, russian astronomer Stanislav Short of the telescope astronomical station Tau has said the comet poses no danger and that such objects pass by our planet all the time without incident.
Space.com indicates “comet C2017S3 will be about 70 million miles (112 million km) from Earth at its closest approach. The comet will then head toward the sun, swinging around our central star on Aug. 16 and then zipping back out to the distant reaches of our solar system. Right now, the comet is too close to the sun to be visible, but it may be visible later in August after it rounds the sun and comes around again, Paul Chodas, the manager for the Center for Near-Earth Object Studies at the Jet Propulsion Laboratory, told Live Science”.
What is the Main Difference Between an Asteroid and a Comet?
The main difference between asteroids and comets is their composition, as in, what they are made of. Asteroids are made up of metals and rocky material, while comets are made up of ice, dust and rocky material. Both asteroids and comets were formed early in the history of the solar system about 4.5 billion years ago. Asteroids formed much closer to the Sun, where it was too warm for ices to remain solid. Comets formed farther from the Sun where ices would not melt. Comets which approach the Sun lose material with each orbit because some of their ice melts and vaporizes to form a tail.
