caption_attribution_description: English: Comparison of best-fit size of the exoplanet Kepler-4 b with the Solar System planet Neptune, as reported in the Extrasolar Planets Encyclopaedia[1] as of 2010-10-03. ↑ Extrasolar Planets Encyclopaedia (2010-09-30). Retrieved on 2010-10-03.
context_page_description: Kepler-4b, initially known as KOI 7.01, is an extrasolar planet first detected as a transit by the Kepler spacecraft. Its radius and mass are similar to that of Neptune; however, due to its proximity to its host star, it is substantially hotter than any planet in the Solar System. The planet's discovery was announced on January 4, 2010 in Washington, D.C. along with four other planets that were initially detected by the Kepler spacecraft and subsequently confirmed by telescopes at the W.M. Keck Observatory.
