Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 15.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 1.4 million years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 8648 years in a starship at a tenth of light speed.
  • Distance. 865 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1161.

Saying hello

  • Say hello. A radio message and its reply would take 1730 years round-trip.

Standing on it

  • A year here. A full year lasts just 402 Earth days.

By the numbers

  • Size. About 12.6× the width of Earth.
  • Volume. About 2000 Earths could fit inside it.
  • Mass. Roughly 2702× Earth's mass — about 8.5 Jupiters.
  • Your weight. You'd weigh about 17.0× your Earth weight standing here.
  • Temperature. Around 841°C — hotter than a self-cleaning oven.

How we found it

  • Discovery. Found by Bohyunsan Optical Astronomical Observatory using the radial velocity method.

About HD 19615 b

HD 19615 b is a common exoplanet. It lies about 864.8 light-years from Earth, has an equilibrium temperature near 1,114 K, spans roughly 12.6 Earth radii and weighs about 2,701.54 Earth masses.

About 12.6× the width of Earth.

How to see it

Like any astronomical target, HD 19615 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 HD 19615 b is a common exoplanet

HD 19615 b scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 5 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Hot Jupiter — 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.
