By combining numerous Hubble observations taken over a 3-year period with ground based observations, a team of astronomers led by G. Fritz Benedict and Barbara E. McArthur has deduced the inclination of the nearest exoplanet's orbit around its parent star Epsilon Eridani and found it to be aligned with the star's debris disk.
