And you can see it with just a small telescope.
It's probably best to catch it at its closest approach to Earth on July 14, 2022, although a supermoon on July 13 may light up the sky, which means you may want to spot it now while the skies are still dark.Experts are unclear at this point about just how big the comet's nucleus is. According to NASA solar system ambassadors Eddie Irrizarry and Kelly Kizer Whitt, it is estimated that the comet falls between a range of 11 and 100 miles wide.
ven at its nearest, it will still be farther away from us than the average distance between Earth and Mars. The size of the comet's tail, or coma, is also being debated by astronomers. The trail of dust and gases behind C/2017 K2 is estimated to be anywhere between 81,000 and 500,000 miles across. If the name Comet PanSTARRS seems familiar, that’s because there are a lot of them. Pan-STARRS is a sky survey that is focused on discovering new asteroids, comets, supernovae, and other celestial objects. When first discovered by Pan-STRRS, C/2017 K2 was 1.49 billion miles from the sun, 16 times farther away than the Earth is from the sun.Now, C/2017 K2 is expected to pass some 168 million miles from Earth.
However, there's no telling how it will behave the closer it gets to the sun. It could suddenly become more active and brighter, or it could fall apart and disappear entirely leaving behind just a trail of dust.at a mind-boggling speed of 47,200 mph .
