Trivia

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 2.7 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 238.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 1526 years in a starship at a tenth of light speed.
  • Distance. 153 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1873.

Saying hello

  • Say hello. A radio message and its reply would take 305 years round-trip.

Standing on it

  • A year here. A full year lasts just 55 Earth days.

By the numbers

  • Size. About 13.2× the width of Earth.
  • Volume. About 2300 Earths could fit inside it.
  • Mass. Roughly 855× Earth's mass — about 2.7 Jupiters.
  • Your weight. You'd weigh about 4.9× your Earth weight standing here.
  • Temperature. A scorching 193°C on average.

How we found it

  • Discovery. Found by McDonald Observatory using the radial velocity method.

Cosmic context

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

About HD 37605 b

HD 37605 b is an uncommon exoplanet. It lies about 152.6 light-years from Earth, has an equilibrium temperature near 466 K, spans roughly 13.2 Earth radii and weighs about 854.96 Earth masses.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, HD 37605 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 37605 b is an uncommon exoplanet

HD 37605 b 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.
