Star system features
g May be a binary, but companion is unconfirmed

Known planets
g Though there are no extrasolar planets confirmed, but star is considered a good candidate to contain terrestrial planets like the Earth.

Habitable zone
g The distance from the star where an Earth-type planet with liquid water would be stable is centered around 0.92 AU. At this distance, the planet would have an orbital period of almost 324 days.
g The star probably is not a good place for Earth-like life. First, it is too young to host any life-bearing planets. Secondly, about once a century is suffers from superflares. These coronal mass ejectionsrelease between 100 and 10 million times more energy than the largest flares ever observed on the sun, making the star brighten for an hour to a week by up to 20 times. If our sun were to produce a large superflare, Earth's ozone layer would be destroyed, and ice on the daylight side of moons as far out as those of Jupiter or even Saturn would be melted, producing vast floodplains that refreeze after the flare subsides.
