Voyager 1
The most distant human-made object.
- classification
- Interstellar spacecraft
- system
- Beyond the heliopause
Voyager 1 crossed the heliopause into interstellar space in 2012 and continues returning measurements from the outer edge of the Sun's influence. Its distance grows continuously, so any stated figure is only accurate as of the date given.
- Class
- Interstellar spacecraft
- Location / system
- Beyond the heliopause
- Distance
- About 170 AU from the Sun in 2026 (increasing roughly 3.6 AU per year; check NASA's live tracker for the current value)
Only values with an established scientific consensus are listed. Where a quantity is uncertain or model-dependent, it is discussed in the sections below rather than stated as data.
Overview (starter entry, expanded review pending)
Voyager 1 crossed the heliopause into interstellar space in 2012 and continues returning measurements from the outer edge of the Sun's influence. Its distance grows continuously, so any stated figure is only accurate as of the date given.
Spacecraft telemetry
Voyager 1's position and environment are reconstructed from radio tracking and measurements returned by its remaining instruments.
- What remains least constrained about Voyager 1?Composition, internal structure, formation history or local environment can require different observations and may remain model-dependent.
Items above are unresolved. Hypotheses are labelled as such and are not presented as confirmed findings.
