With exoplanet Ross 128b in the news, we pay a visit to the star that sustains this potentially habitable exoplanet.

No matter where you look the fecundity of the universe is manifest. Consider exoplanets. Since the first was discovered in 1992, astronomers have been piling them on like mashed potatoes at Thanksgiving. Today we know of more than 3,700. Of those, 53 may be potentially habitable.

The most recently discovered potentially life-friendly planet — and in some ways the most exciting — is Ross 128b, which circles the red dwarf star Ross 128 in the constellation Virgo. Located just 11 light-years away, it's the second closest Earth-sized planet within the habitable zone of its star.

Astronomers estimate that temperatures on Ross 128b range from –76° to 68° F (–60° to 20° C). You could argue that's even more temperate than than that of Earth and likely warm enough for liquid water to pool on its surface. What's more, its star experiences far fewer massive flares compared to other red dwarfs, making conditions more hospitable to potential life.

While you and I aren't going to see Ross 128b anytime soon, we can have the pleasure of seeing its host sun, Ross 128. Currently visible in a dark sky before the start of dawn, this newsy red dwarf is just 1.1° southwest of 3rd-magnitude Beta (β) Virginis. To find the dwarf and its mind's-eye planet, center Beta in the field of view and use the AAVSO map to star-hop right to it.

Eager to see it for myself, I got up the first clear morning after the news of the discovery broke last week. Oh gosh, how easy could it be. Pale red and magnitude 11.2, Ross 128 is bright enough to spot in telescopes as small as 4 inches (10 cm). Mingled in the star's light were photons from its closely orbiting and perhaps habitable planet, a satisfying thought.

Some 80% of the Milky Way's stars are red dwarfs, yet not a single one is visible to the naked eye. Being something of an introvert, I cotton to these shy suns. The brightest, Lacaille 8760 in Microscopium, shines at magnitude 6.7. Despite their retiring nature, they make for fertile exoplanet hunting grounds. A tiny dwarf feels a much stronger — and more easily measurable — tug by an orbiting planet compared to a bigger star like our Sun.

If we're patient and smart enough not to destroy ourselves, we'll have an even better view of Ross 128 in due time. The star is moving towards us at 31 km/sec and will become our nearest stellar neighbor around 81,000 AD, when only 6.2 light-years will separate the two Earths.

We celebrate Thanksgiving this week, a time to be grateful for all we have. As we reflect on the ups and downs that sustain our lives, feel free to take another helping at the table, including this stellar cranberry.
