Comet C/2013 UQ4 (Catalina) has been observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet is seen glowing brightly in infrared wavelengths on July 7, 2014, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago.

C/2013 UQ4 takes more than 450 years to orbit the sun once and spends most of its time far away at very low temperatures. Its orbit is also retrograde, which means that the comet moves around the sun in the opposite direction to the planets and asteroids.

The comet was originally thought to be an asteroid, as it appeared inactive when discovered by the Catalina Sky Survey on October 23, 2013. NEOWISE also observed the comet to be inactive on New Year’s Eve, 2013, but since then the comet has become highly active, allowing astronomers around the world to observe it. The comet’s activity should decline as it once again returns to the cold recesses of space.

Those dates are certainly incorrect. Sorry to inform you of your miscalculation but this universe and world has only been around for a few thousand years. The world for sure because the magnetic plates would’ve clasped in already over time. Meaning it can’t last that long as the plates are already growing unsteady. And well there is no way to trace back humans or animals to billions or millions of years. And if you are basing your dates off of carbon dating I’m so very sorry for you, but that is very inaccurate work. It cannot give you the exact dates. And obviously in the past they have been way off
