Jupiter stations retrograde today, pausing before its long apparent backtrack. Venus and Mars stand about sixty degrees apart today, a sextile, traditionally read as an easy, cooperative angle. The Moon is in Aquarius, a young crescent growing in the evening sky.

What does Jupiter mean in astrology?

Jupiter is the planet of growth and meaning, and it takes about twelve years to circle the zodiac, spending roughly a year in each sign.

Because it is slow, Jupiter is a background theme rather than a daily one: a whole year of a life tends to share its sign. It rules Sagittarius and, classically, Pisces.

Traditionally it signifies expansion, generosity, teaching, travel and belief. The catch that older astrologers were clear about is that growth is not automatically good, since things grow past their proper size too.

On a daily page Jupiter usually shows up in an aspect rather than an ingress, and it reads as the wider frame around a smaller event.
