Spotting the icy body with naked eyes will be fairly difficult owing to the distance and those with telescopes will also have to put some effort into tracking the faint glow of comet Leonard's tail. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. This means that the peak brightness of a comet depends significantly on its distance from the Sun. Comets actually have two tails―a dust tail and an ion (gas) tail. NASA Spots Biggest Comet Ever—500 Trillion Ton Ice Ball Headed This Way The comet's journey started over 3.7 trillion miles (6 trillion kilometers) away from the sun, or 40,000 astronomical units. The dashboard displays the next five Earth approaches to within 4.6 million miles (7.5 million kilometers or 19.5 times the distance to the moon); an object larger than about 150 meters that can approach the Earth to within this distance is termed a potentially hazardous object.
