  Since the discovery of Kepler-10, the system has received considerable
interest because it contains a small, rocky planet which orbits the star in
less than a day. The system's parameters, announced by the Kepler team and
subsequently used in further research, were based on only 5 months of data. We
have reanalyzed this system using the full span of 29 months of Kepler
photometric data, and obtained improved information about its star and the
planets. A detailed asteroseismic analysis of the extended time series provides
a significant improvement on the stellar parameters: Not only can we state that
Kepler-10 is the oldest known rocky-planet-harboring system at 10.41 +/- 1.36
Gyr, but these parameters combined with improved planetary parameters from new
transit fits gives us the radius of Kepler-10b to within just 125 km. A new
analysis of the full planetary phase curve leads to new estimates on the
planetary temperature and albedo, which remain degenerate in the Kepler band.
Our modeling suggests that the flux level during the occultation is slightly
lower than at the transit wings, which would imply that the nightside of this
planet has a non-negligible temperature.
