English: The irregular satellites of Neptune. Plotted by a program written by Eurocommuter. The position of a satellite represents its orbit’s semi-major axis a in Gm (horizontal axis) orbit’s inclination i in degrees (vertical axis). the size of the circle illustrates the satellites's size relative to others:
Neptune brightened about 10% between 1980 and 2000 mostly due to the changing of the seasons. [177] Neptune may continue to brighten as it approaches perihelion in 2042. The apparent magnitude currently ranges from 7.67 to 7.89 with a mean of 7.78 and a standard deviation of 0.06. [18] Prior to 1980, the planet was as faint as magnitude 8.0. [18]
It also has a decidedly strange orbit that was highly elliptical and tilted. At times it is actually closer to the sun than Neptune. It has a methane, nitrogen and carbon monoxide atmosphere and a ...
The larger one, with about 18 billion times the mass of our sun (right), would encompass all the planets in the solar system with room to spare. The smaller one is about 150 million times the mass of our sun (left), which would be large enough to swallow up everything out to the asteroid belt, just inside the orbit of Jupiter. Short title
