Galaxy information

Triangulum Galaxy

A face-on spiral galaxy whose future entries will depend on confirmed observations rather than fictional worlds.

Travel reality

Distance at human spacecraft speeds

At light speed2.73 million years299,792 km/s

Physical reference only; a spacecraft with mass cannot reach light speed.

At 10% of light speed27.3 million yearsHypothetical 29,979 km/s

No operational human spacecraft can approach this cruise speed.

At Parker Solar Probe peak4,257.75 million yearsAbout 692,000 km/h

Parker reaches this record near the Sun; it is not an interstellar cruise capability.

At Voyager 1 speed48,143.14 million yearsAbout 17 km/s relative to the Sun

A practical comparison with a spacecraft on an interstellar trajectory.

Life potential

How likely is other life somewhere in Triangulum Galaxy?

Triangulum is smaller than Andromeda but still contains enough stars to make life plausible somewhere inside it.

Editorial probability of other life59%
Possible but weakly constrained

Why this score?

  • It is a spiral galaxy with active star-forming regions.
  • Its smaller stellar population lowers the score relative to larger galaxies.
  • Direct knowledge of its planets and biosignatures is extremely limited.

This estimate is intentionally broad and speculative.

Structure

Triangulum is a smaller spiral galaxy viewed close to face-on, making its arms and star-forming regions easy to study.

Scientific interest

Its vigorous star formation provides a useful comparison with the Milky Way and Andromeda.

Catalog policy

No individual habitable planets are claimed here. The request system measures public interest until reliable discoveries can support real entries.
