On October 21, comet C/2025 A6 Lemmon will make its closest approach to Earth — approximately 89 million kilometers, according to the Solar Astronomy Laboratory of the Institute for Space Research of the Russian Academy of Sciences and the Institute of Solar-Terrestrial Physics of the Siberian Branch of the Russian Academy of Sciences. This event attracts the attention of both professional astronomers and space enthusiasts.
«Comet C/2025 A6 Lemmon will make its closest approach to Earth in three days, at a distance of approximately 89 million km,» the specialists specified. The object is moving from the constellation Canes Venatici towards Boötes, with the nearest bright reference star being Arcturus.
The comet is primarily of interest to astrophotographers: with high-precision instruments, it appears as an «exceptionally beautiful» object. However, due to its faint visibility, it is almost impossible to spot it with the naked eye or ordinary binoculars.
For comparison, most comets close to Earth remain faint and require special instruments. International practice shows that such flybys allow for the collection of important data about the composition of comets, their tails, and their interaction with the solar wind.
