Star and planets drawn to scale: the star is 87 times as wide as HIP 68468 Ab, so only its edge is in view. Orbits spaced as in the star system view.
Estimated: this planet doesn't transit its star, so its size is inferred, not measured
HIP 68468 Ab, from the Extrasolar Planets Encyclopaedia (found 2016). Measured: 2.89 Earth masses, 0.0297 AU, a 5857 K G-type star. Composition inferred from a estimated bulk density of 0.84x Earth's, modeled rather than measured since this isn't a transiting planet, a little low for bare rock but leaving room for too little gas to change what it is — read as rock and iron, with a day locked to its 1.8-day year, as anything orbiting this close would be.
Surface. Molten surface with lava flows, volcanic activity everywhere
Minimal - too hot to retain
No atmosphere - exposed to radiation and temperature extremes
