On 2011 February 1 the Kepler mission released data for 156453 stars observed from the beginning of the science observations on 2009 May 2 through September 16. There are 1235 planetary candidates with transit-like signatures detected in this period. These are associated with 997 host stars. Distributions of the characteristics of the planetary candidates are separated into five class sizes: 68 candidates of approximately Earth-size (R_p_<1.25R_{earth}_), 288 super-Earth-size (1.25R_{earth}_<=R_p_<2R_{earth}_), 662 Neptune-size (2R_{earth}_<=R_p_<6R_{earth}_), 165 Jupiter-size (6R_{earth}<=R_p_<15R_{earth}_), and 19 up to twice the size of Jupiter (15R_{earth}_<=R_p_<22R_{earth}_). In the temperature range appropriate for the habitable zone, 54 candidates are found with sizes ranging from Earth-size to larger than that of Jupiter. Six are less than twice the size of the Earth. Over 74% of the planetary candidates are smaller than Neptune. Multi-candidate, transiting systems are frequent; 17% of the host stars have multi-candidate systems, and 34% of all the candidates are part of multi-candidate systems.
