Comet Lemmon is already visible in the sky – it will not return to Earth until more than a thousand years later

To the starry sky a new comet has appeared, which has been named Lemmon.

However, the comet is still so faint that it can only be found in the sky with binoculars or a telescope.

At the end of October, the comet may be visible even to the naked eye, he says astronomical association Ursa in its announcement.

Comet stays above the horizon all night at the end of October.

The best time to spot Lemmon is estimated to be between October 20th and 5th. November.

In October–November, the weather in Finland is usually cloudy. That’s why the opportunity to see a comet can rarely arise.

Around midnight it can be seen in the northern sky and in the morning in the northeast. In the north, however, Lemmon can be seen quite low, and it may be difficult to notice.

At its highest, Lemmon is in the dark evening and morning sky. In early November, it starts to disappear from the horizon.

Lemmon moves as he progresses from Ursa Major and Otava to other constellations. An electronic star chart can help you find a comet.

“Around October 20, the bright orange star Arcturus is a good starting point for the search. The comet can be found above it,” says the comet expert Veikko Mäkelä Ursan in the bulletin.

Lemon’s the name is C/2025 A6 in the lists of objects in the starry sky.

Comet Lemmon got its name from the Lemmon Observatory in the United States. The comet was discovered there last January by telescopes.

Lemmon is coming towards the Sun from far away, behind the planet Neptune. The origin of the comet is in the region of space where many icy bodies orbit the Sun.

Lemmon last visited Aurinko 1,350 years ago. When it finally passes the Sun this November, its orbit will change slightly.

That’s why it returns to the Sun faster than before, “already” after about 1,150 years.

Comet cores are very icy material. Their matter begins to gasify as the comet approaches the Sun and heats up.

A round gas veil then begins to develop around the comet’s nucleus. It’s called a coma.

The sun’s radiation and the particle stream usually blow the core material into a tail. Comets that have come close to the Sun are also called comets.

Comet Lemmon’s tail also stands out when viewed through binoculars. The coma itself appears as a foggy ball.
