# Triton, Moon of Neptune

**Triton** is a Moon that orbits round the planet Neptune. Its orbit circumference, the total distance it travels round its planetary parent is 2,229,016.54 km. The furthest it gets from its orbital parent (apoasis) is 354,759 km. Its mass is estimated/calculated at being 21,394,990,550,895,500,000,000 kg. Its density has been calculated at being 2.059 g/cm3. Its volume is 10,384,058,491 km3.

It was discovered in the year 1846 by W. Lassell.

The orbital period, i.e. the period it takes to complete an orbit round Neptune is 5.877 days. The figure is also known as the sidereel period. The figure comes from N.A.S.A..

The Semi-Major Axis of the orbit is 354,759 km, which is the furthest point from the centre to the edge of an elliptical point.

The temperature IN the atmosphere is about 38 K.

The equatorial circumference of Triton is 8,503.7 km. The mean radius, that is the average radius of Triton is 1353.4 km. The surface area of Triton is 23,017,714.99 km2. The surface gravity of the said item is 0.779 m/s2. The average orbit velocity, that is the speed at which it orbits is 15,803.2 km/h.

The orbital inclination, the angle at which Triton orbits in relation to the orbital plane is 156.865 degrees. The orbital eccentricity is 0, it is the degree at which Triton orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.
