Hale Bopp The Great Comet Of 1997 It is difficult to predict the maximum brightness of new comets with any degree of certainty, but hale–bopp exceeded most predictions when it passed perihelion on april 1, 1997, reaching about magnitude −1.8. its massive nucleus size made it visible to the naked eye for a record 18 months. Also called the great comet of 1997, comet c 1995 o1 (hale bopp) is a large comet with a nucleus measuring approximately 37 miles (60 kilometers) in diameter. this is about five times the size of the object hypothesized to have led to the demise of the dinosaurs.
Comet Hale Bopp Facts For Kids Hale bopp was a relatively fresh giant, arriving from the distant oort cloud with enormous volatile reserves still intact. this fundamental difference explains why hale bopp dramatically outperformed halley in terms of brightness, tail complexity, and sustained activity. Comet hale bopp was first observed on july 22, 1995 by amateur astronomers alan hale and tom bopp, when it was about 3.5 au from the sun. its perihelion (closest approach to the sun) of 0.9 au occurred on april 1, 1997. It was discovered independently on july 23, 1995, by alan hale and thomas bopp, two american amateur astronomers, at the unusually far distance of 7.15 astronomical units (au; about 1 billion km [600 million miles]) from the sun, well beyond jupiter ’s orbit. Most comets are discovered when they are relatively near the sun, but at the time of its discovery hale bopp was ridiculously far away — more than 7 astronomical units (au) from the sun, and roughly 670 million miles (1.1 billion km) from earth.

Huge cometary nucleus: comet hale bopp’s nucleus, or icy core, was estimated to be about 25 miles (40 kilometers) in diameter, making it one of the largest cometary nuclei ever observed. Comet hale bopp is believed to be a large comet with a nucleus up to 40 kilometres wide. it was discovered in july 1995 by two american astronomers working independently, alan hale and thomas bopp. In 1997, the world witnessed one of the most spectacular celestial events of the century: hale bopp, a massive comet visible to the naked eye for an unprecedented 569 days. It is difficult to predict the maximum brightness of new comets with any degree of certainty, but hale–bopp exceeded most predictions when it passed perihelion on april 1, 1997, reaching about magnitude −1.8. its massive nucleus size made it visible to the naked eye for a record 18 months.
