It would trap alot of geothermal energy. If there is water, it's probaby concentrated sulfuric acid. Sulfuric acid breaks down cellulose, so woody plants probably would not exist there.

On the other hand, the star system would be very old. Perhaps the geothermal cycle of the planet would have wound down enough that volcanism would be no worse than Earth's. But what else would be different? Would the star lack a magnetic field to protect against cosmic rays? Higher gravity might mean lower mountain peaks, and more equally distributed rainfall. Who knows what the ratio of land area to ocean area is.

If the star is ultra-old, then so would the planet. Would a planet orbiting so close to such an old star for such a long time be tidally locked? If so, one side of the planet would be in perpetual daylight. That could lead to interesting transition zones at the day-night boundary. And with such slow rotation, there would be no coriolis effect, high winds but no cyclonic storms.

If there is anything alive there, it would probably be super-evolved. But that doesn't mean interstellar travel is within its means. Super-evolved might mean it has achieved an unachievable equilibrium with its environment. Maybe it IS its environment. Who knows.
