Earth revolves around the Sun once in 365 days in an orbit whose semi-major axis is taken as 1 AU.
(a) A newly discovered dwarf planet orbits the Sun in a nearly circular path of radius 4.0 AU. Calculate its orbital period in Earth years.
(b) Express the period obtained in part (a) in days (take 1 year = 365 days).
