Trivia

Could we get there?

  • Verdict. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 28.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 2.5 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 16.2 thousand years in a starship at a tenth of light speed.
  • Distance. 1619 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 407.

Saying hello

  • Say hello. A radio message and its reply would take 3237 years round-trip.

Standing on it

  • A year here. A full year lasts just 4.2 Earth days.

By the numbers

  • Size. About 2.5× the width of Earth.
  • Volume. About 15.6 Earths could fit inside it.
  • Mass. About 6.8× the mass of Earth.
  • Your weight. You'd weigh about 1.1× your Earth weight standing here.
  • Temperature. Around 784°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by K2 using the transit method.

Cosmic context

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

About K2-282 b

K2-282 b is an uncommon exoplanet. It lies about 1,618.7 light-years from Earth, has an equilibrium temperature near 1,057 K, spans roughly 2.5 Earth radii and weighs about 6.8 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, K2-282 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 K2-282 b is an uncommon exoplanet

K2-282 b scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.

That score comes from 4 science badges — Confirmed exoplanet, Sub-Neptune, Multi-planet system and Distant (>1000 ly) — 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.
