A newly discovered comet, C/2025 F2 (SWAN), is offering skywatchers a glimpse into the early solar system. The comet, first spotted March 29 by amateur astronomers michael Mattiazzo and Vladimir Bezugly, is making its closest approach to Earth in approximately 70,000 years.
Mattiazzo and Bezugly used the Solar Wind Anisotropies (SWAN) instrument aboard the ESA/NASA’s Solar and Heliospheric Observatory (SOHO) to make the initial discovery.
A Visitor from the Oort Cloud
Originating from the Oort Cloud, a distant region believed to be the source of long-period comets, C/2025 F2 (SWAN) follows a near-parabolic orbit. This marks the first opportunity for humans to observe this celestial object as it nears the sun.
prime Viewing Time
Astronomers estimate that C/2025 F2 (SWAN) will reach perihelion, its closest point to the sun, on May 1. At that time,it will be approximately 0.333 astronomical units (AU) from the sun. As the comet approaches the sun,its brightness is expected to increase,potentially reaching a visual magnitude of between 3.6 and 5.0.
Under dark skies with minimal light pollution, the comet may become visible with binoculars or even to the naked eye.
The optimal viewing period for C/2025 F2 (SWAN) is between mid-April and early May. Currently, in mid-April, the comet can be observed in the northeastern sky before dawn, traversing the constellations Pegasus and Andromeda. Toward the end of April, it will shift to the northwestern sky after sunset, appearing near the Pleiades star cluster in the constellation Taurus around May 1.
An “Easter Comet” with Ancient Secrets
Dubbed the “Easter comet” due to its appearance coinciding with Easter celebrations, C/2025 F2 (SWAN) presents a unique opportunity for both professional and amateur astronomers. The comet contains pristine material from the solar system’s early formation, untouched by the sun’s heat and radiation, making it a valuable subject for studying the solar system’s evolution.
This comet is a very valuable time capsule, carrying ancient ice and dust from the early formation of the solar system.

Tips for Spotting the Comet
For the best viewing experience, observers are advised to seek out dark locations away from city lights. Star-tracking applications such as Stellarium or SkySafari can assist in locating the comet’s position in real-time.
A Green Glow
C/2025 F2 (SWAN) is also notable for its distinct green hue,a result of diatomic carbon gas (C2) that glows when exposed to sunlight. As it approaches the sun, the comet’s speed is estimated to exceed 60 kilometers per second, according to data from sky monitoring sites.
