The Sun and Moon

There are no eclipses this month.

As seen from the Earth, the Sun is moving from the constellation Capricornus to the constellation Aquarius.

Expect very high tides on 27 February when the Full Moon coincides with perigee.

Like last month, both Saturn and Jupiter are occulted by the Moon. The eastern United States and Canada can watch Saturn disappear behind the limb of the First Quarter Moon from about 22 UT on 20 February. Jupiter will fall victim to the waxing gibbous Moon two days later from around 0 UT for observers in northern Canada, Siberia, and northern and western Europe.

The Planets

The word planet is derived from the Greek word for "wanderer." Unlike the background stars, planets seem to move around the sky, keeping mostly to a narrow track called the ecliptic, the path of the Sun across the stars.
Mercury
The best viewpoint to see this elusive planet is in the southern hemisphere. Look for Mercury climbing ever higher in the sunrise sky as it moves around the constellations Capricornus and Sagittarius.
Venus
The "evening star" is very low in the sunset sky. Look for it in the constellations Capricornus and Aquarius.
Mars
The red planet sets before midnight in the constellation Pisces.
Jupiter
Jupiter is occulted by the Moon on 23 February. It can be found in the constellation Gemini.
Saturn
The Moon occults the ringed planet on 20/21 February. With east quadrature on 27 February, this is a particularly interesting time to observe the shadow interplay between the disk and the rings of the planet. Saturn is lurking near the Hyades open star cluster in the constellation Taurus.
Uranus
Because Uranus reaches conjunction by mid-month, it cannot be seen in the constellation Capricornus.
Neptune
Like Uranus, Neptune is too near to the Sun to be seen.
Pluto
This smallest of the planets is in the constellation Ophiuchus, and rises in the early morning hours.

Minor Planets, Comets and Meteors

Minor Planets
3 Juno reaches opposition in the constellation Hydra. At eighth magnitude, though, you will need optical aids to see it.
Comets
There are no naked-eye comets visible this month.
Meteors
The waning crescent Moon should cause no problems for southern hemisphere observers watching the Alpha Centaurids meteor shower.

The Celestial Sphere

Constellations are patterns of stars in the sky. The International Astronomical Union (IAU) recognises 88 different constellations. The brightest stars as seen from the Earth are easy to spot but do you know their proper names? With a set of binoculars you can look for fainter objects such as nebulae and galaxies or some of the closest stars to the Sun.

Descriptions of the sky for observers in both the northern and southern hemispheres are available for the following times this month. Subtract one hour from your local time if daylight savings time is in effect. (Note: These times are approximate.)

Northern Hemisphere : 45° N

Southern Hemisphere : 30° S
