Vestibular disease is one of the most common neurological presentations in veterinary neurology and can be one of the most challenging. The vestibular system or apparatus, as it is also known, is responsible for maintaining balance, posture, and the bodyâs orientation in space.
Mercury is the planet with the shortest period of revolution of approximately 88 Earth days. However, Mercuryâs period of rotation is about 59 Earth days. A planetâs period of revolution is the time it takes for one complete spin around the sun. This is different from a planetâs period of rotation, which is the spinning of a planet on its own axis. More information on this question: 1. Mercury: One year on planet Mercury takes just 87.97 earth days.
In addition to being the planet closest to the Sun, Mercury is also the smallest by mass. If you ignore the former planet Pluto, it is also the smallest by surface area, as well. The planet has the most eccentric orbit: at perihelion it is 46,001,200 km from the Sun and at aphelion it is 69,816,900 km.The planetâs short orbital period(87.969 Earth days) and slight axial tilt combine to make the day on Mercury(116 Earth days) longer than the year.n addition to being the planet closest to the Sun, Mercury is also the smallest by mass. If you ignore the former planet Pluto, it is also the smallest by surface area, as well. The planet has the most eccentric orbit: at perihelion it is 46,001,200 km from the Sun and at aphelion it is 69,816,900 km.
