[4] The exoplanet was found by using the radial velocity method, where periodic Doppler shifts of spectral lines of the host star suggest an orbiting object.

It is now hypothesized that Jupiter's movement in the Solar System may have cleared the way for the rocky inner planets, including Earth, to form.

According to Jorge Meléndez, who led the University of São Paulo, Brazil team that discovered HIP 11915 b, "the quest for an Earth 2.0, and for a complete Solar System 2.0, is one of the most exciting endeavors in astronomy".

[1] This means that there is the chance that HIP 11915 may have undetected terrestrial planets closer in, at a distance ranging from 0.5–1.6 AU.

Megan Bedell, from the University of Chicago and lead author of the paper, concludes: “After two decades of hunting for exoplanets, we are finally beginning to see long-period gas giant planets similar to those in our own Solar System thanks to the long-term stability of planet hunting instruments like HARPS.
