If skies are clear, individuals can view the conjunction by looking at the Moon and finding the brightest star in the sky next to the Moon, which will be Jupiter.
But in constructing the first atmospheric model that has the orbital dynamics of a star-planet-moon system fully included, astronomers Duncan Forgan, at the Royal Observatory in Edinburgh, and David Kipping, at the Harvard Smithsonian Center for Astrophysics in Cambridge, turn that idea on its head.
Kepler-37b is a tad larger than our heavenly dance partner, the Moon, and whizzes round a star much like our Sun, with two larger planets in its system for company.
