Astronauts have not visited Venus. Venus has an extremely inhospitable climate. Probes barely survive the descent. Humans would stand no chance.
No. The space shuttle was designed for low-Earth orbit, not travel between planets. Currently there are no manned spacecraft capable of interplanetary travel. Venus is much too hot for people to survive there
Nope, not yet and there are no plans for any to visit in the future.
yes lots of space probes
There haven't been any probes sent to Eris.
It's an object in outer space; that's basically what astronomy is about - studying objects in outer space.

No, only a few unmanned spacecraft have visited Venus. A manned flyby mission was planned by the US in the 1970s following the successful moon landings of the Apollo program, but it was cancelled.

The Russians have sent missions to Venus and have discovered that it is a most inhospitable place with an atmosphere that is 95% carbon dioxide, and a surface air pressure of 93 atmospheres. Its chronic global warming gives it a surface temperature of 400-500 degrees C.
Spacecrafts have never visited Pluto, but the New Horizons mission is on its way there.
Spirit and Opportunity are two.
