CFHTWIR-Oph 98 b

A confirmed world orbiting CFHTWIR-Oph 98 A.

Discovered 2020 · Imaging

A gas giant

20.85 Earth radii, Jupiter-class (Jupiter is 11.2). At only 2479.1 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.

The orbit

Its year takes 8,040,000 Earth days (22012.3 Earth years).

Temperature and starlight

Its equilibrium temperature (the airless-world estimate) is about 1,527 °C. Hot enough to melt copper; any surface would glow.

Its sun

Its star is a red dwarf (2,320 K surface), type M9-L1: small, dim, flare-prone, and destined to outlive the Sun many times over.

How we found it

It was directly imaged, one of the rare planets actually photographed as its own point of light, possible only for young, hot, wide-orbiting giants. The discovery was announced in 2020 from Hubble Space Telescope.

Everything above is computed from the archive’s measured values for this planet. Where a quantity is missing, the statement is omitted rather than guessed.

About this record

The measured values come from the NASA Exoplanet Archive, and any missing value has not been determined yet; the Atlas never fills gaps with guesses. More standout worlds: Proxima b, TRAPPIST-1e, K2-18 b, 55 Cancri e, and the detection methods that found them all.
