Which is the most boring exoplanet?

Bland exoplanet OGLE 2005 BLG-390Lb and the shitty little red dwarf it orbits. Illo: Beschizza

Every other week, it seems, an exciting new discovery crops up in a distant star system. The latest is Wolf 1061c, the closest Earth-like world yet found, barely a probe's throw away at 14 light years. But this got me thinking: which is the least interesting exoplanet yet discovered?

To my inexpert eye, OGLE 2005 BLG-390Lb looks like a terrifically boring world. Though it was scientifically interesting early in the exoplanetary race due to its tiny size and vast distance from Planet Earth, this merely makes it the Rand Paul of planets.

It's at least 18,000 light years away, so we're not getting there until we can reach billions of other, more interesting worlds. And when someone does get there, they'll find what appears to be rocky blob well out of its star's habitable zone.

It's covered in abundant elements such as ammonia and nitrogen, all frozen solid because it's so cold. Its star is believed to be a red dwarf, which is to say, very boring in its own right.

"I wish I'd had a chance to visit OGLE 2005 BLG-390Lb," no-one will ever say.

But I could, of course, be completely wrong. I'm not an astronomer, after all. Tell us in the comments which exoplanet you are most bored by!
