Trivia

Could we get there?

Verdict. Hopelessly far for any craft humanity can build today.

Getting there

Aboard Voyager 1. ≈ 10.9 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 967 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 6193 years in a starship at a tenth of light speed.
Distance. 619 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1407.

Saying hello

Say hello. A radio message and its reply would take 1239 years round-trip.

Standing on it

A year here. A full year lasts about 2.8 Earth years.

By the numbers

Size. About 12.9× the width of Earth.
Volume. About 2147 Earths could fit inside it.
Mass. Roughly 1554× Earth's mass — about 4.9 Jupiters.
Your weight. You'd weigh about 9.3× your Earth weight standing here.
Temperature. A frigid -73°C — colder than dry ice.

How we found it

Discovery. Found by Lick Observatory using the radial velocity method.

Cosmic context

Crowded system. One of at least 2 planets orbiting its star.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, TIC 139270665 c is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why TIC 139270665 c is an uncommon exoplanet

TIC 139270665 c scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Gas giant, Eccentric orbit and Multi-planet system — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
