Trivia

Hard to believe

  • A year in a day. Its entire year is over in 3.2 hours. Birthdays here would come round faster than meals.

What it actually is

  • Hugging its star. It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.

Find it in the sky

  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around June — that's when to go looking.

Standing on it

  • A year here. A full year lasts just 0.1 Earth days.

By the numbers

  • Mass. Roughly 785× Earth's mass — about 2.5 Jupiters.

How we came to know it

  • A very new science. The first planet confirmed around a Sun-like star was found in 1995. Every exoplanet humanity knows of has been discovered inside a single lifetime.

How we found it

  • Discovery. Found by South African Radio Astronomy Observatory (SARAO) using the pulsar timing method.

About M62H b

M62H b is a common exoplanet. It weighs about 785.04 Earth masses, completes an orbit every 0.13 days and belongs to a system of 1 known planets.

It orbits closer to its star than Mercury does to the Sun, completing a lap in less time than Mercury takes.

How to see it

Like any astronomical target, M62H 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 M62H b is a common exoplanet

M62H b scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.

That score comes from 2 science badges — Confirmed exoplanet and Ultra-short period — 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.
