Trivia

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 110.9 million years at Voyager 1's speed (17 km/s).
Fastest probe ever. ≈ 9.9 million years even at the Parker Solar Probe's 192 km/s.
At 10% light speed. ≈ 63.1 thousand years in a starship at a tenth of light speed.
Distance. 6311 light-years from Earth.

Look-back time

Look-back time. Its light left before the last ice age ended.

Saying hello

Say hello. A radio message and its reply would take 12.6 thousand years round-trip.

Standing on it

A year here. A full year lasts just 6.5 Earth days.

By the numbers

Size. About 12.3× the width of Earth.
Volume. About 1874 Earths could fit inside it.
Temperature. Around 946°C — hotter than a self-cleaning oven.

How we found it

Discovery. Found by Kepler using the transit method.

Cosmic context

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

About Kepler-730 b

Kepler-730 b is a rare exoplanet. It lies about 6,311.2 light-years from Earth, has an equilibrium temperature near 1,219 K, spans roughly 12.33 Earth radii and completes an orbit every 6.49 days.

One of at least 2 planets orbiting its star.

How to see it

Like any astronomical target, Kepler-730 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 Kepler-730 b is a rare exoplanet

Kepler-730 b scores 38 points on Spacedle's rarity scale, which places it in the rare tier. Another 8 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Multi-planet system, Found by Kepler 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.
