On Sunday (Dec. 2), the giant planet Jupiter reached opposition with the sun, lining up directly opposite the sun in the sky. That means it's a great target for stargazers, who can see it shine brightly all night long this week. Within the next two weeks, two more solar system bodies will also reach opposition right alongside Jupiter: Vesta and Ceres. Seven years ago, these would be described as the solar system's two largest asteroids, which are a large group of small bodies whose orbits mostly lie between the orbits of Mars and Jupiter. But in 2006, the International Astronomical Union, the governing body of astronomy, reclassified Ceres as a dwarf planet, grouping it together with Pluto and other Kuiper Belt objects. Starry Night Software Nine days later, on the morning of Dec. 18, Ceres will also reach opposition, right between the “horns” of Taurus, the Bull.
