Hmm...this looks interesting.
(Space Daily) Further observations of Zeta Leporis have enabled researchers to precisely gauge the size of this dust dusk. Additionally, according to Cowen, research finds that the location of the dust is at a distance of 3 astronomical units (AU) from Zeta Leporis, quite similar to the location of the solar system's asteroid belt, stretching from 2.1 to 3.3 AU from the sun.
Noting that asteroids are leftovers from the planet-making process in the solar system, Cowen reports that, while still a young star, Zeta Leporis is old enough to have formed planets. These new studies and findings "support the thought that Earthlike planets may exist" according to Michael Jura of the University of California, Los Angeles who observed the dust in the disk surrounding Zeta Leporis to find its radius.
Unfortunately the star is 70 plus light years away, give or take a day. It also orbits a blue star, which may or may not be suitable for Earth plants (that is if we every took the chance of traveling there).
