The planets around star HR 8799 are unusually easy to detect because they're massive (heftier than Jupiter), young (still glowing with heat from their formation), and widely separated.
Planet b is twice as far from its star as Pluto is from the Sun. Even Planet e, the innermost, is about as far out as Uranus.
