The first comet discovered in 2026, officially named C/2026 A1, is already generating a lot of buzz. scientific community International. Identified in January of this year by amateur astronomers, the object is expected to pass dangerously close to the Sun between April 4th and 5th, in a rare trajectory.
The observation took place in Chile, the orbital analysis was done in Italy, and the interest is explained by the comet’s potential to become visible even during the day, should it survive the extreme heat.
Right from the start, what is known is clear: it is a comet from the family of so-called “sungrazers,” bodies that practically graze the surface of the sun.

OC/2026 A1 was detected while still very distant, which is unusual, and this raises expectations about its size, brightness, and potential scientific impact.
The first comet discovered in 2026 was observed on January 13th from San Pedro de Atacama, in the Chilean desert. The discovery was made by a group of French amateur astronomers who are part of the MAPS program, using an 11-inch telescope.
The object received the official designation C/2026 A1, granted by the International Astronomical Union. Since then, new analyses have begun to reveal that this is no ordinary comet.
One of the first warnings came from orbital analysis. Italian astronomer Piero Sicoli identified similarities between the trajectory of C/2026 A1 and that of Comet Pereyra, observed in 1963. This suggests that both may be fragments of the same ancestral body.
These objects belong to the so-called Kreutz family, a group of comets known for approaching the Sun extremely closely. Many of them end up disintegrating, while others become part of astronomical history.
Kreutz comets follow highly elongated orbits and pass at very close distances to the Sun. They are all believed to be fragments of a huge comet that broke apart about a thousand years ago.
Therefore, each new object in this family helps to reconstruct this history of fragmentation. In this context, the first comet discovered in 2026 could be a key piece of this cosmic puzzle.
One of the most surprising factors is that C/2026 A1 already had a magnitude close to 18 when it was about 2 astronomical units from the Sun. In simple terms, this means that it was already detectable even from a great distance.
This early detection indicates that the nucleus may be larger than normal for comets of this family. According to preliminary analyses, this may indicate that the nucleus of the first comet discovered in 2026 is relatively large, with a diameter of up to 2,4 kilometers.

Furthermore, initial images show a small tail and a diffuse greenish coma. This coloration is caused by the emission of diatomic carbon, a gas released when the comet’s ice begins to sublimate.
OC/2026 A1 is located in the constellation Eridanus, just over 200 million kilometers from Earth. As it approaches the Sun, its activity tends to increase.
Extremely close passage of the Sun defines the future of C/2026 A1
The most impressive feature of C/2026 A1 is its predicted close approach to the Sun. Estimates indicate that it will pass about 783 kilometers from the solar surface. Although this number seems large, it represents a minimal distance in astronomical terms.
This critical moment, called perihelion, defines two possible scenarios. On the one hand, the intense heat and gravitational forces could completely destroy the comet. On the other hand, if it survives, it could become a rare spectacle, with intense brightness and even visibility during the day.
Previous cases help to understand what might happen. In 1965, Comet Ikeya-Seki withstood an even closer passage to the Sun and became one of the brightest of the century.
Back in 2011, Comet Lovejoy also attracted attention by crossing the solar corona, but it disintegrated days later. Therefore, the fate of C/2026 A1 remains uncertain, making its observation even more exciting.
Even if it doesn’t survive perihelion, C/2026 A1 is already considered valuable to science. Comets are true time capsules, as they preserve materials formed in the early stages of the Solar System.
Thus, observing how this object reacts to extreme heat helps to understand the composition and evolution of these icy bodies. Therefore, regardless of the outcome, C/2026 A1 is already considered one of the most interesting comets of recent years.
