Low on the horizon from Rio de Janeiro
These clear the horizon but stay low, so trees and buildings may hide them: Centaurus (~18°, south-western) · Crux (~14°, south-western) · Cassiopeia (~4°, northern) · Boötes (~4°, north-western) · Taurus (~3°, eastern) · Perseus (~2°, north-eastern) · Carina (~2°, southern).
Out of reach from Rio de Janeiro
At Rio de Janeiro's latitude these never climb above the horizon, so you can't see them from here at any time of year: Orion, Canis Major, Gemini, Ursa Major, Leo. To catch them, you'd need to travel toward the Northern Hemisphere.
