Comet Pan-STARRS appears increasingly bright in the morning sky. Ele should maintain magnitude between 3 and 4 until April 22nd. The best time for observation occurs at dawn, in the east-northeast direction.
Comet C/2025 R3 (Pan-STARRS) was discovered in September 2025 by the Pan-STARRS 2 telescope, at Havaí. Ele approaches Sol and Terra this month, which creates favorable conditions for anyone who wants to see it. In places with dark, clear skies, the object may appear faintly to the naked eye, although binoculars or small telescopes make viewing easier. A photograph taken on April 13 shows the comet’s long, thin tail, with several artificial satellites passing close to the nucleus.
Current visibility of the comet
Comet Pan-STARRS is in the constellation Pégaso. Ele appears low on the east-northeast horizon about an hour to 90 minutes before sunrise. The current brightness varies around magnitude 4 to 5, according to recent observations, and should reach its peak intensity close to perihelion, scheduled for April 19th. Depois from that date, the object is closer to Terra, with passage scheduled for April 26th or 27th.
In regions of the northern hemisphere, the observation window remains good until the weekend. The sky without a new moon in the middle of the month helps the comet stand out against the dark background. Observadores need an obstacle-free horizon to locate the point of diffuse light, which may show an elongated ionized tail.
- The comet appears about 90 minutes before sunrise
- The main direction is east-northeast
- 10×50 binoculars make detection easier
- The object is close to Grande Quadrado of Pégaso
- The tail appears long and thin in captured images

Details of the photograph registered on Japão
An astronomy enthusiast captured the image of comet Pan-STARRS at around 4:10 am on April 13, in the city of Echizen, province of Fukui. Masahisa Hayashi waited for about an hour for the clouds to dissipate. The photo reveals the extended tail and straight lines left by artificial satellites that crossed the field of view near the nucleus.
Hayashi, 68, had already photographed other comets. Ele Highlighted the elongated appearance of the tail on this occasion. The image was taken in the open terrain of Centro of Aprendizagem of Floresta Yatsusugi, in Betsuin-cho. The record occurs at a time when the comet is still at a reasonable distance, but gains luminosity as it approaches Sol.
The photographer started the challenge on April 12th. The next day, he captured the comet low in the eastern sky, through thin clouds. Diversas Straight lines where artificial satellites passed also appeared in the photo. The long, thin tail caught the attention of the experienced observer.
Origin and orbital characteristics
Comet Pan-STARRS belongs to the Oort cloud and completes a long orbit. The last passage close to Sol happened around 170 thousand years ago. Após this current approach, the object must leave the solar system without returning. Ele does not represent a risk of collision with Terra, as it passes at a safe distance.
Perihelion occurs on April 19, when the comet comes within approximately 0.5 astronomical units of Sol. The closest approach to Terra is expected for the end of April. Essas distances allow the ice and core materials to release gases and dust, forming the visible coma and tail.
The comet was discovered on September 8, 2025. Ele is classified as a long-period, hyperbolic comet. The orbit indicates that it came from distant regions of the solar system. Após perihelion, the object may gain additional brightness by forward scattering of sunlight.
Practical tips for observation
Anyone planning to observe the comet should choose locations away from light pollution. The ideal time varies depending on latitude, but always occurs in the pre-dawn period. Aplicativos astronomy or star charts help you identify the exact position relative to Pégaso’s bright stars such as Markab.
The comet moves quickly relative to the stellar background. Therefore, observation on consecutive nights shows changes in position. On clear days, brightness can allow detection even in moderate urban conditions, but ideally dark skies remain. Após On the 22nd, the object loses altitude and becomes more difficult to see from the northern hemisphere before sunrise.
Observers in the Southern Hemisphere will have a better opportunity in late April and early May, when the comet will appear in the evening sky. The new phase Lua helps during peak visibility. Binóculos are recommended for most people, as the comet still requires clear skies to be consistently seen with the naked eye.
What to expect in the coming days
Comet Pan-STARRS continues to brighten as it approaches perihelion. Depois of this phase, it continues towards the closest approach to Terra. Para observers in the northern hemisphere, visibility at dawn gradually decreases after April 22nd.
Amateur and professional astronomers follow the event with cameras and telescopes. The images show details of the tail and nucleus activity. The phenomenon offers a rare opportunity to see a long-period comet in a good position in the sky.
The brightness may vary depending on the comet’s activity. Previsões indicate that it can reach magnitude close to 3 on the most favorable days. Após perihelion, the object moves between Sol and Terra, which can increase brightness due to light scattering effect.
