At first glance, you'll notice that many of the planets in Kate Winslet's chart are around the Ascendant (middle left of wheel). In this closer look, the many planets in Libra are highlighted. See the crescent Moon symbol there? That means her Moon is in the sign of Libra. Look out, she's a triple Libra! This means her 'Big Three' (Sun, Moon and Rising) are in Libra, the air sign known for beauty, innate sense of justice, and a bright mind.
Her Moon is at 13 degrees Libra, and forms a stellium with Mercury, the Sun and Pluto. A stellium is a cluster of planets in close degree on the chart. A stellium means those energies are co-mingled, adding to their power. And in this example, the Libra life path is supported by the Moon's emotional base and Mercury's perceptive filter. And that adds power to the Sun's life purpose for Kate Winslet.
