Confirmed exoplanet · Database record + computed analysis

NGTS-2 b

A confirmed world orbiting NGTS-2, 1,162.4 light-years away.

1,162.4 light-years (356.4 pc) Discovered 2018 · Transit

A gas giant

17.88 Earth radii, Jupiter-class (Jupiter is 11.2). At only 235.2 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky. Orbiting this close, it is a classic 'hot Jupiter', a giant that migrated inward from where it formed.

The orbit

Its year, one full orbit, takes just 4.5 Earth days.

Temperature and starlight

Its equilibrium temperature (the airless-world estimate) is about 1,195 °C. Hot enough to melt copper; any surface would glow. It receives 1,085.3 times the starlight Earth gets.

Its sun

Its star is hotter than the Sun (6,478 K, F5 V), burning brighter and faster.

How far is that, really?

At 1,162 light-years, tonight's light from this system left it around the year 863. A Voyager-speed probe would need roughly 20,565,727 years to get there.

How we found it

It was found by the transit method: the planet crosses its star's face on schedule, dimming it by a tiny, repeating fraction. The dip's depth gives the planet's size. The discovery was announced in 2018 from Next-Generation Transit Survey (NGTS).

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.
