The listed value is the approximate present distance from Earth. Interstellar destinations move, but the difference is negligible compared with the enormous journey time at current spacecraft speeds.
Complete world information
GJ 1002 b
It lies in or near the system's habitable-zone region, but no atmosphere has been confirmed.
Scientific status
No exoplanet is confirmed habitable or inhabited. Habitable-zone position only means that liquid surface water could be possible under the right atmospheric conditions. Rate the Earth percentages are editorial comparison scores, not scientific probabilities.

Could other life exist on GJ 1002 b?
GJ 1002 b is treated as a potentially habitable candidate, so this site assigns it a moderate editorial probability for simple non-human life.
Candidate for simple life
Why this score?
- Rate the Earth habitability comparison score: 55%.
- Atmosphere clue: Unknown.
- Host-star context: M-type red dwarf.
- The catalog flags this world as a potentially habitable candidate.
This probability is an editorial astrobiology estimate based on public characteristics, not a formal scientific measurement.

Travel calculation
How long would the journey take?
Straight-line arithmetic is compared with real mission history. Actual trajectories depend on orbital mechanics, acceleration, braking, launch windows and gravity assists.
A physical reference only. A spacecraft with mass cannot reach light speed.
No operational spacecraft can sustain this interstellar cruise speed.
Still far beyond current spacecraft propulsion.
Parker reaches this speed only very close to the Sun; it is not an interstellar cruise speed.

Research guide
What we know, and what we do not know
What is directly known
The planet itself is not resolved as a detailed globe. Its existence and properties are inferred mainly through radial velocity, together with measurements of the host star.
What remains unknown
Surface geography, oceans, continents, clouds and living organisms have not been directly observed. Atmosphere and composition may also remain uncertain.
What is known
GJ 1002 b is a nearby low-mass planet discovered with high-precision radial-velocity measurements.
Habitability limits
The planet does not transit from our viewpoint, so radius and atmosphere are not directly known.
Why it stands out
Its nearby distance makes the system a future target for direct characterization.
