NASA’s Hubble Space Telescope has confirmed that the Bernardinelli-Bernstein comet has the largest icy nucleus ever seen. The nucleus is the central part of the comet, usually consisting of rock, dust and gas. The nucleus of the Bernardinelli-Bernstein comet is around fifty times larger than most known comets. Officially known as C/2014 UN271, the Bernardinelli-Bernstein comet was discovered by chance in November 2010. It has an estimated diameter of around 129 kilometres and a mass of around 500 trillion tonnes. The comet has an estimated temperature of minus 348 degrees Fahrenheit. Currently, the Bernardinelli-Bernstein comet is on a 3-million-year-long elliptical orbit. It is travelling at a speed of 22,000 miles per hour from the edge of the solar system towards us According to NASA, it is unlikely that the Bernardinelli-Bernstein comet will become a threat to us. Even at its closest, the comet is still predicted to only reach a point farther away from Saturn. This situation is also not likely to occur till 2031.
