It will transit or pass due south at 7:25 p.m, and will set at 2:56 a.m. Jupiter is a wonderful sight in telescopes with its cloud bands and its moons which change positions each night. Saturn will be the next planet to rise at 12:34 a.m. in the east southeast. It’s located in eastern Virgo. Saturn will pass due south at 5:44 a.m. It will rise before midnight by the end of the month.

The planet Jupiter is the largest, most massive planet in the solar system. It contains more mass that all the other planets, asteroids, and moons twice over. As Isaac Asimov once said: “The solar system contains the sun, Jupiter and debris.” Jupiter, named after the king of the Roman gods, processes majestically through the Zodiac, spending about one year in each of the constellations. This year it’s Taurus, next year it will be Gemini. Saturn, on the other hand limps along, taking nearly 30 years to make the same circuit. It’s the god of old age. Jupiter throws its weight around. It’s responsible for the asteroid belt, keeping a planet from forming there. It deflects some comets from the inner solar system, but also sends others on in.

This morning the planet Saturn will appear above and right of the crescent moon. They should be visible until a bit after seven a.m. The moon will be slipping eastward morning by morning, and by Thursday it will appear near the planet Venus. The moon’s movement around the earth with respect to the sun is called the synodic month, or a lunation. It is the period between one new moon to the next of about 29 and a half days. It is the basis for lunar calendars such as the Jewish and Islamic calendars. The moon’s crescent can be waxing or waning, growing fatter or thinner. It is now waning, and next week when we see the moon in the evening its phase will be waxing. The moon is just an illuminated ball in space.
