Local sky character in Grenoble
Northern mid-latitudes · northern hemisphere · 218 m elevation
- The north celestial pole stands 45.2° above the horizon, so stars within 45° of it never set from here.
- About 85.5% of the whole sky rises above the horizon at some point in the year from this latitude.
- The Milky Way's core in Sagittarius culminates about 15.8° up, staying low, so a clear southern horizon matters.
- At 218 m elevation, roughly 3% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Grenoble is a town-scale settlement, so the edge of the built-up area is often dark enough for the Milky Way on moonless nights.

Radiant in Orion. Visible from both hemispheres. The Moon is 72% lit on peak night, so lunar interference is moderate.
- 2026-10-25 — Full Moon
A 99%-lit Moon washes out faint objects, but lunar terrain along the limb is at its most striking — plan bright targets and planets instead of deep sky.
- 2026-11-05 — Taurids peak — up to 5/hour
Radiant in Taurus. Favours the Northern Hemisphere, which includes Grenoble, Rhône-Alpes, France. The Moon is 18% lit on peak night, so lunar interference is low.
- 2026-11-09 — Darkest night of the coming month
The Moon is only 0% illuminated, giving the least lunar interference in the next 30 nights — the best window for the Milky Way and faint deep-sky targets from Grenoble, Rhône-Alpes, France.

- What is the stargazing light pollution level in Grenoble, Rhône-Alpes, France?
- Grenoble, Rhône-Alpes, France is a small city — typically Bortle class 4–5 (rural/suburban transition), where the Milky Way core can be glimpsed on clear, moonless nights.

- What should I plan for observing near Grenoble, Rhône-Alpes, France?
