⭐A new interstellar object of cometary nature
approaching the inner Solar System, named 3I/ATLAS (alternative designation C/2025 N1), has been discovered by the "Asteroid Terrestrial-Impact Last Alert System" (ATLAS) survey.
Its orbit has an exceptionally high eccentricity of
e=6.18 . It should brighten up to magnitude 10 at the beginning of November this year. » 3I/ATLAS complete information. - The Sun is in Gemini, the Moon is Waxing Gibbous in Virgo
