HD 205739

HD 205739 is a yellow-white dwarf (spectral type F7 V). It is about 90 parsecs away from the Sun.

A Jupiter-like planet has recently been detected in a Mercury-like eccentric orbit around this star.

There is a trend in the results which may point to an additional companion further from its star.
