What it would be like
TOI-2094 b is a super-Earth — larger than our planet but likely still rocky or ice-rich. Whether it has a thin atmosphere like Mars or a crushing one like Venus remains unknown.
Surface gravity is about 1.2g — noticeably heavier what you're used to on Earth.
With an equilibrium temperature around 3°C, this planet sits in the temperature range where liquid water could potentially exist on the surface — a key ingredient for life as we know it.
An orbital period of 19 days makes the year 19.4× shorter than Earth's. You'd celebrate your birthday more often here.

Tiny dip in starlight as the planet crosses in front of its star
A transit photometer watches a star nonstop and measures its brightness to ~0.01%. When a planet passes between us and the star, the star dims briefly — the deeper the dip, the bigger the planet. This is how Kepler and TESS found most known exoplanets.

How far is 163 light-years?
- A light beam leaving Earth right now would arrive in 163 years.
- At Voyager 1's speed (17 km/s), the trip would take approximately 2.9 million years.
- A radio signal sent today would arrive in 163.2 years — and the reply wouldn't come back for twice that.
Earth Similarity Index
80/1000 — Nothing like Earth100 — Identical to Earth
ESI combines radius similarity and equilibrium temperature similarity. Earth = 100. Mars ≈ 73. Venus ≈ 44. This score reflects two physical parameters only — not atmosphere, water, or magnetic field.
