But life there would not be peaceful, as a massive debris disc
around the star, increases the chance of hits from asteroids and comets.
The system includes comets, orbiting gas clouds, and an enormous debris disc
that in our solar system would extend from Neptune's orbit to nearly 2,000 times the distance from the Earth to the sun.
They observed that the planet is not aligned with Beta Pictoris' (its star's) main debris disc
but is aligned to and potentially interacting with an inner warped component disc.
But just last year, British astronomer Jane Greaves and her colleagues discovered an enormous dust-laden debris disc
around Tau Ceti.
Because of the Herschel's sensitive far-infrared capabilities and its rich dataset, astronomers have been able to resolve bright emission around Kappa Coronae Borealis (CrB, or Kappa Cor Bor), indicating the presence of a dusty debris disc.
This is the first 'retired' star that we have found with a debris disc and one or more planets," said Amy Bonsor of the Institute de Planetologie et d'Astrophysique de Grenoble, and lead author of the study.
Mark Wyatt from the University of Cambridge, lead author of the paper focusing on the debris disc around 61 Vir.
Herschel is finding a correlation between the presence of massive debris discs and planetary systems with no Jupiter-class planets, which offers a clue to our understanding of how planetary systems form and evolve," stated Goran Pilbratt, ESA's Herschel project scientist.
These models indicate that the mass of the debris disc
around Jupiter, from which the moons formed, was several tens of a per cent of the mass of giant planet; And yet only 2 per cent is enough to make the moons we see today.
The latest insights into the formation and structure of our own 'Mark I' solar system, both planets and other smaller bodies, as well as many types of other planetary systems are to be found in chapters on protoplanetary and debris discs
, terrestrial planets and giant planets.
The debris discs
are remnants of the formation of the planets.
are composed of dust resulting from collisions among larger bodies like planetary embryos or asteroids.
