    Description Beta Pictoris is an A type star, 63 lightyears away from our own Solar System. The star is host to a debris disk and a planet. Using high spectroscopic observations, astronomers were able to measure the length of a day on bet Pic b: 8.1 hours. The planet or material in orbit around it may have been responsible for a transit-like event observed in November 1981.edit

    Planet sizes

    The following plot shows the approximate sizes of the planets in this system The Solar System planets are shown as a comparison. Note that unless the radius has been determined through a transit observation, this is only an approximation (see Lissauer et al. 2011b).

    Habitable zone

    The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). This is only an estimate, using the star's spectral type and mass. Note that if no green band is shown in the plot, then the planet's orbit is far outside the habitable zone. The equations of Selsis, Kasting et al are used to draw the inner and outer boundaries.
