Trivia

What makes it special

  • Lava world. Its surface is likely an ocean of molten rock.

Could we get there?

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

Getting there

  • Aboard Voyager 1. ≈ 7.6 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 673.3 thousand years even at the Parker Solar Probe's 192 km/s.
  • At 10% light speed. ≈ 4312 years in a starship at a tenth of light speed.
  • Distance. 431 light-years from Earth.

Look-back time

  • Look-back time. The light you'd see left around the year 1595.

Saying hello

  • Say hello. A radio message and its reply would take 862 years round-trip.

Standing on it

  • A year here. A full year lasts just 2.6 Earth days.

By the numbers

  • Size. About 2.5× the width of Earth.
  • Volume. About 15.3 Earths could fit inside it.
  • Mass. About 7.7× the mass of Earth.
  • Your weight. You'd weigh about 1.2× your Earth weight standing here.
  • Temperature. Around 1462°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 TOI-4495 b

TOI-4495 b is a rare exoplanet. It lies about 431.2 light-years from Earth, has an equilibrium temperature near 1,735 K, spans roughly 2.48 Earth radii and weighs about 7.7 Earth masses.

Its surface is likely an ocean of molten rock.

How to see it

Like any astronomical target, TOI-4495 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-4495 b is a rare exoplanet

TOI-4495 b scores 42 points on Spacedle's rarity scale, which places it in the rare tier. Another 4 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Sub-Neptune, Lava world, 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.
