HD 213240 b is an extrasolar planet located approximately 133 light-years (41 parsecs) away in the constellation of Grus, orbiting the star HD 213240. This planet has a mass class of I (super-Jupiter) and the appearance class of W (Water giant). It has an orbital period of 882.7 days or 76.27 megaseconds. The orbital distance is 1.92 astronomical units or 287 gigameters or 9.31 microparsecs. The orbital eccentricity is 42.1%. The closest distance and farthest distance are 1.11 AU and 2.73 AU respectively; the difference and quotient between q and Q are 1.62 AU and 2.46 times respectively. The angular separation between a planet and a star as seen from Earth is 47.12 milliarcsecond (mas).

The origin of this known planet came from the country of Switzerland and the astronomer Santos. The date was on April 4, 2001 and the method was Doppler spectroscopy.
