Plot of the orbits of the 61 Virginis system.
<p>Orbit and debris disk data taken from Vogt et al. (2010), The Astrophysical Journal 708 (2), 1366–1375 "A Super-Earth and Two Neptunes Orbiting the Nearby Sun-like Star 61 Virginis"

The configuration is given in Table 4 and the orbits are taken to be coplanar. Planetary positions are given for the epoch JD 2453369.166, as given in the paper. The orbits are taken to be astrocentric rather than barycentric. This is because the true masses of the planets are unknown, so it is not possible to compute the actual positions of the barycentres.
