For units in astronomy, see astronomical system of units. The astronomical unit (symbol au, AU or ua) is a unit of length, roughly the distance from the Earth to the Sun. However, that distance varies as the Earth orbits the Sun, from a maximum (aphelion) to a minimum (perihelion) and back again once a year.

Sena is one of those names that is as obscure in the Western World as it is simple and straightforward. Sena exists as a name in a range of languages and cultures and may be pronounced like Senna (with a soft e) or Sienna. Sena is also a place name, a surname, the name of several groups of people, and the name of a genus of moth as well as a kind of wine, among other things. The similar Cinna from The Hunger Games may make Sena more plausible as a first name.
