Related: About this forumKepler-88 has a new king! Planet three-times Jupiter's mass discovered in alien star system
By Gemma Lavender 5 hours ago
Orbiting its sun-like star every four days, the giant could play a role in sparking life on rocky worlds.

It appears that planetary heavyweight Kepler-88 c, which orbits the sunlike star Kepler-88, is no longer the gravitational god of the exoplanets in the Kepler-88 system, according to a new study. A new world was recently confirmed in the system, tipping the scales at three times the mass of solar system giant Jupiter.
Led by a team of astronomers at the University of Hawaii Institute for Astronomy (UH IfA), the research which is based on six years of data taken from W.M. Keck Observatory on Mauna Kea in Hawaii uncovered a previously undetected third exoplanet orbiting Kepler-88. Named Kepler-88 d, the newfound planet completes slow-moving laps around its host star every four years.
It was the keen telescopic eye of the High-Resolution Echelle Spectrometer (HIRES) instrument affixed to the 10-meter Keck I telescope that revealed to lead author Lauren Weiss, a Beatrice Watson Parrent Postdoctoral Fellow at UH IfA, her team had made a game-changing discovery.
"At three times the mass of Jupiter, Kepler-88 d has likely been more influential in the history of the Kepler-88 system than the so-called King, Kepler-88 c, which is only one Jupiter mass," Weiss said. "So maybe Kepler-88 d is the new supreme monarch of this planetary empire the empress."

Methinks theres a typo in the article above. Four years is far more likely.

(7,520 posts)2. Headline is wrong
Article says four years, headline four days. That happens a lot since the headline writer and article author are often different people.

(32,017 posts)5. n/p 4 days is ridiculously fast for a gas giant.
A typo was the most logical explanation.
