Though it has never been measured accurately, scientists think the nucleus is between 24 and 43 miles in diameter, whereas most comets are only a few miles wide. A larger nucleus releases more gas and dust. Hale-Bopp is thought to have formed between the orbits of Jupiter and Neptune, according to a recently published study . The comet's brightness is currently about 400 times less than what can be seen with the naked eye. Eventually, Hale-Bopp will escape the effects of the solar wind and be no more than a hard, frozen nucleus.
Researchers hope to then gauge the size of the nucleus with powerful telescopes.
