Local sky character in Porto Velho
Tropical / equatorial latitudes · southern hemisphere · 90 m elevation
- The south celestial pole stands 8.8° above the horizon, so stars within 9° of it never set from here.
- About 57.6% 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 69.8° up, clearing the horizon haze comfortably.
- The Large Magellanic Cloud only reaches about 29.1° altitude, so it is a low, seasonal target rather than a year-round one.
- At 90 m elevation, roughly 1% of the atmosphere's mass is already below you, which measurably reduces extinction near the horizon.
Porto Velho is a mid-sized urban area — bright constellations and planets work from town; faint deep-sky objects need a drive out.
