“Introducing Comet Leonard” is copyrighted by Dan Bartlett. NASA has permission to show it and we don't, so it isn't on this card.
See it on NASA's siteComet C/2021 A1, also known as Comet Leonard, was discovered as a faint smudge in January 2021. Its orbit will bring it into the inner Solar System, passing near Earth and Venus in December, before it loops around the Sun in January 2022. Although comets are difficult to predict, some estimates suggest Comet Leonard may become visible to the unaided eye in December.
