## Definition: Year

A year is the time between two recurrences of an event related to the orbit of the Earth around the Sun. In astronomy, the Julian year is a unit of time, defined as 365.25 days of 86,400 SI seconds each (no leap seconds), or 31,557,600 seconds total.

We default to using the Gregorian year on this site, but you can select a specific type of year by entering the full name like "Julian year".

## Definition: Nanosecond

The SI prefix "nano" represents a factor of 10-9, or in exponential notation, 1E-9.

So 1 nanosecond = 10-9 arcseconds.

The definition of a second is as follows:

A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.7×10-7) of a circle. It is the angular diameter of an object of 1 unit diameter at a distance of 360×60×60/(2pi) (approximately 206,265 units), such as (approximately) 1 cm at 2.1 km, or, directly from the definition, 1 astronomical unit at 1 parsec.
