While naked-eye comets are rare C/2023 A3 could be among the brightest in a decade.
A video NASA released on Wednesday shows the debris caused by the Double Asteroid Redirection Test mission spacecraft slamming into the asteroid Dimorphos. / Joseph DePasquale )A newly-discovered bright comet visible to naked eyes – even from the suburbs of larger cities – will whiz past Earth next year.C/2023 A3 could be a comet of a decade"Comet C/2023 A3 is no threat to Earth," said Veres, who is also a research scientist at the Minor Planet Center.
Currently, the comet is between Jupiter and Saturn and is faint, only accessible by larger telescopes. Only a coma – the nebulous envelope around the nucleus of a comet – is visible, Veres said. But once it comes closer to the sun, the sublimation of ices could lift more dust from its surface. "However, nobody else was able to observe the object on the following nights, thus, it was removed from the confirmation page," he said.
The International Astronomical Union eventually decided to name the comet, giving the credit to Purple Mountain and ATLAS, and MPC announced its orbit and designation as C/2023 A3 .
