Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 6.6 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 585 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 3746 years in a starship at a tenth of light speed.
Distance. 375 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1651.

Saying hello

Say hello. A radio message and its reply would take 749 years round-trip.

Standing on it

A year here. A full year lasts just 2.7 Earth days.

By the numbers

Size. About 5× the width of Earth.
Volume. About 123 Earths could fit inside it.
Mass. About 44.1× the mass of Earth.
Your weight. You'd weigh about 1.8× your Earth weight standing here.
Temperature. Around 930°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Transiting Exoplanet Survey Satellite (TESS) using the transit 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, TOI-1288 b 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 TOI-1288 b is an uncommon exoplanet

TOI-1288 b scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 5 science badges — Confirmed exoplanet, Neptune-like, Multi-planet system, Blasted by starlight and Found by TESS — 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.
