Star and planets drawn to scale: the star is 8.2 times as wide as HD 14082 Bb, so only its edge is in view. Orbits spaced as in the star system view.

Estimated: this planet doesn't transit its star, so its size is inferred, not measured

HD 14082 Bb, from the Extrasolar Planets Encyclopaedia (found 2024). Measured: 1720 Earth masses, 5.74 AU, a 5941 K G-type star. Composition inferred from a mass of 1720 Earths, which is giant territory whatever its 0.82x density suggests, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Surface. No solid surface - thick gaseous envelope with possible rocky core deep within

Gas Giant
Magnetic FieldExtreme Activity
HD 14082 Bb has 86.0% hydrogen and helium, combined with a mass of 1720.0x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Classification Criteria:
✓ Hydrogen + Helium: 86.0% (>60% required)✓ Mass: 1720.0x Earth (>10x required)

Reading HD 14082 Bb’s atmosphere

Dominant elements: H, He, O, C, NThis is what a telescope would measure while HD 14082 Bb crosses in front of its star: starlight passes through the atmosphere and spreads into a rainbow band. Each dark line marks a wavelength the atmosphere absorbed.Every element absorbs its own signature wavelengths — hydrogen always darkens the same two spots, calcium another pair, and so on. Astronomers match the lines in a real spectrum against a library of these signatures to say what an atmosphere is made of, light-years away, without ever visiting. A deeper line generally means more of that element is present.HD 14082 Bb sits about 129 light-years away, found by the astrometry method. Most catalogued distances trace back to parallax: as Earth orbits the Sun, a nearby star appears to shift very slightly against the distant background stars, and the size of that shift gives its distance directly.

New: Stand on Your Moons 🌒

A planet's surface view isn't the only ground any more. Press the surface button on a planet with moons and it asks where to stand: the planet itself, or any moon still in orbit, each tagged with what it became — ocean, ice, carbon, volcanic. Every moon gets its own ground and sky from its own physics: airless rock under a black sky, ice cracked by geysers over a hidden sea, sulfur plains shaking with eruptions, or orange haze you can't see the sun through. And hanging over the horizon, there's the planet you built.
