February 2026 holds a series of astronomical phenomena that attract skywatchers in different regions of the planet. The month highlights a parade of six planets visible just after sunset and an annular solar eclipse, known as the ring of fire, scheduled for February 17. Esses events occur amid favorable observation conditions in places with low light pollution.
The planetary parade reaches its peak on February 28, when Mercúrio, Vênus, Júpiter, Saturno, Urano and Netuno appear aligned in the night sky. The annular eclipse, in turn, has main visibility at Antártida, with partial phases in southern parts of América, Sul and África. Especialistas recommend suitable equipment to make the most of these natural alignments.
Full moon begins sequence of events
The full Lua of February 2, traditionally known as Lua da Neve, marks the beginning of the month’s astronomical highlights. Ela reaches peak brightness accompanied by the star Regulus, in the constellation of Leão, creating a conjunction visible to the naked eye in several regions.
In some areas of the northern hemisphere, there is a brief occultation of Regulus by Lua. Esse phenomenon reinforces the initial visibility of the month and sets the stage for subsequent events.
Parade of planets gradually takes shape
From February 8th, the planets begin to position themselves for main alignment. Mercúrio and Vênus appear low on the southwest horizon just after sunset, while Júpiter appears higher in the east and Saturno in the southwest.
Uranus sits between Júpiter and Saturno, and Netuno is close to Saturno, although both require binoculars or telescopes for clear observation. Essa configuration evolves over the weeks and reaches its best moment at the end of the month.
Peak alignment on February 28
On February 28, six planets form an arc visible in the night sky shortly after dusk. Vênus, Júpiter, Saturno and
- Mercury: low on the western horizon;
- Venus: intense brightness near the horizon;
- Saturn: intermediate position in the southwest;
- Jupiter: high in the eastern sky;
- Uranus and Netuno: visible with binoculars.
This alignment follows the ecliptic and offers a rare opportunity for simultaneous observation. Locais far from urban centers provide the best conditions for recording the phenomenon.
Annular solar eclipse of February 17
The annular solar eclipse occurs on February 17, when Lua Nova is positioned between Terra and Sol, but does not completely cover the solar disk. Isso creates the effect known as a ring of fire, with a luminous border around the lunar silhouette.
Maximum override lasts about two minutes and 20 seconds on the remote Antártida. Regiões from the extreme south of América from Sul, including parts of Argentina and Chile, and from the south of África observe partial phases of the phenomenon.
At Brasil, the eclipse is not directly visible, even in southern areas. Observadores depend on live broadcasts to follow the event.
Experts warn against using certified sunscreens in case of partial observation. Eye safety remains a priority in any visual contact with the Sol.
Zodiacal light complements observations
Mid-February favors the observation of the zodiacal light, a faint triangular glow caused by the reflection of sunlight off interplanetary dust. Esse false twilight appears about an hour after sunset in dark places.
Visibility improves in the Southern Hemisphere during this period. The phenomenon complements the planetary parade and offers an additional spectacle for nighttime astronomy enthusiasts.
Other highlights of the month
Mercury reaches its greatest eastern elongation on February 20, making it easier to spot in the afternoon sky. On the 24th, Lua approaches the Plêiades cluster, in the constellation of Touro, creating another notable conjunction.
These smaller events enrich the astronomical calendar and allow for continuous observations throughout the month.
Ideal observation conditions
Observation of the February 2026 phenomena benefits from clear skies and low light pollution. Aplicativos of astronomy help in the precise location of the planets and in planning the sessions.
The month combines events visible to the naked eye with others that require simple equipment. Essa variety attracts both beginners and experienced observers in different parts of the world.
