Joseph Smith provides valuable commentary on this subject, explaining that when this sign is seen by the world’s population, they will speculate that “it is a planet, a comet, etc.” He also said that while the wicked will not understand its true significance—attributing it to a natural cause—the righteous will know what it means.
C/2014 UN271 (Bernardinelli-Bernstein), or simply 2014 UN271, is a large Oort cloud comet discovered by astronomers Pedro Bernardinelli and Gary Bernstein in archival images from the Dark Energy Survey.[6] When first imaged in October 2014, the object was 29 AU (4.3 billion km) from the Sun and almost as far as Neptune's orbit. As of 2021, it is currently approaching the Sun at a distance of 20.2 AU (3.0 billion km) and will reach its perihelion of 10.9 AU (just outside of Saturn's orbit) in January 2031.[4]
