Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 3.8 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 335.9 thousand years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 2151 years in a starship at a tenth of light speed.
Distance. 215 light-years from Earth.

Look-back time

Look-back time. The light you'd see left around the year 1811.

Saying hello

Say hello. A radio message and its reply would take 430 years round-trip.

Standing on it

A year here. A full year lasts just 10.3 Earth days.

By the numbers

Size. About 2.5× the width of Earth.
Volume. About 15.3 Earths could fit inside it.
Mass. About 19.1× the mass of Earth.
Your weight. You'd weigh about 3.1× your Earth weight standing here.
Temperature. Around 429°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.

About HIP 97166 b

HIP 97166 b is a common exoplanet. It lies about 215.1 light-years from Earth, has an equilibrium temperature near 702 K, spans roughly 2.48 Earth radii and weighs about 19.1 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, HIP 97166 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 HIP 97166 b is a common exoplanet

HIP 97166 b scores 20 points on Spacedle's rarity scale, which places it in the common tier. Another 4 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Sub-Neptune, Multi-planet system 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.
