The star Rho Cancri B has about the same mass as our Sun, and the planet discovered around it orbits somewhat closer than Mercury orbits our Sun. The mass of the planet is estimated to be 1.1 times the mass of Jupiter. Why, according to our theory of solar system formation, is it surprising to find a planet the size of Rho Cancri B's planet orbiting at this distance?

In the nebular theory, jovian planets form beyond the frost line. In our solar system, this was beyond the orbit of Mars, so it is surprising to find a jovian planet orbiting so close to its star.
