On December 26, 2011, evidence for two extremely short-period planets, Kepler 70b ,Kepler 70c and was announced by Charpinet et al. They were detected by the reflection of starlight caused by the planets themselves, rather than through a variation in apparent stellar magnitude caused by them transiting the star. The measurements also suggested a smaller body between the 2 candidate planets; this remains unconfirmed. If these planets exist, then the orbits of Kepler-70b and Kepler-70c have 7:10 orbital resonance and have the closest approach between planets of any known planetary system. However, later research suggested that what had been detected was not in fact the reflection of light from exoplanets, but star pulsation "visible beyond the cut-off frequency of the star." Further research indicated that star pulsation modes were indeed the more likely explanation for the signals found in 2011, and that the two exoplanets probably did not exist. If Kepler-70b exists, then it has a temp of 7288 K, the same as that of an F0 star. GIMME VIEWS
RECAP: The kepler-70 system has 3 records i.e. the closest planets to each other that is not a binary system, the closest planets to their star and the hottest planets Btw this is outdated.
