Earth is dangerous.
However there are many factors which need to be answered and lets look at our solar system first.
For Humans the following factors need to be taken into account to survive without any protection
Lack of Oxygen- all other planets and moons lack oxygen
Lack of liquid Water- all other terrestrial planets lack liquid water (currently) however it may be present on some moons
high or low temperatures (down to 3 degrees Kelvin and upwards to 700)
high radiation and lack of a magnetic sphere
poisonous or corrosive atmospheres
Other solar systems which meet human habitation requirements might have toxic plants or biota.
