Another exoplanet observed a couple of nights ago from my observatory. Remember that the observation consists of measuring the drop in the star's brightness as the planet passes in front of it: the eclipse produced by the planet as seen from Earth. This is what we can see in the graph above.
From these data we can infer many of the planet's characteristics. In this case, we know that its radius is 1.27 times Jupiter's, although its mass is much smaller. It takes 4.05 Earth days to complete an orbit around its star, which is slightly smaller than our Sun and of spectral type G8.
