How to Photograph Comet K2 – Space.com | Ad On Picture

Comet C/2017 K2 (PANSTARRS), or K2 for short, is currently hurtling through the sky at a speed of about 615 km/s and will make its closest approach to Earth on Thursday, July 14. An exciting time for astronomers and stargazers, as this is one of the largest comets we have seen in quite some time.

The Hubble Space Telescope observed that K2 is about 18 kilometers across (which, to put it in perspective, is twice the size of Mount Everest), with the tail millions of kilometers long. K2 was originally discovered in 2017 when it was between Uranus and Saturn (about 1.5 billion miles from the Sun). Because of its large orbit, this is the only chance we have of seeing it, as it won’t fly by Earth again for a few million years.

Unfortunately, there are no guarantees for comet watching and chances are you will see very little. But there are two main factors that will determine your chance of seeing Comet K2 on July 14 – the weather conditions and your gear. Unfortunately, if it’s cloudy and visibility is poor, you’re out of luck this time. When it comes to equipment, it will likely only be a telescope object, given that it’s about 170 million miles from Earth at its closest point.
