the sun is much much more massive than Neptune
Apparent magnitude is the brightness as viewed from EarthAbsolute magnitude is the brightness as viewed from the same distance - 32 light years.Therefore a star that is twice as bright but further away could have the same apparent magnitude but a different absolute magnitude.
No planet is further from the Sun than Neptune in our solar system. Neptune is the eighth and farthest known planet from the Sun.
The moons of Mars are actually quite small, smaller than any of the known moons of Neptune. It is possible that further observation of Neptune will reveal additional, smaller moons, but at present, the smallest moon of Neptune is over twice the size of the larger of Mars' moons.
No, neither is it even a planet. It is further away from the sun than Neptune.
Neptune is almost 79 times further away from the Sun than Mercury.
Pluto is (usually), but it's only a "dwarf planet".
neptune is futher away from venus but much bigger than it.
Uranus
It is the spacecraft voyager 2 , it is the only spacecraft to visit Neptune, and travel further.
Neptune is the farthest planet from the sun in our solar system.
Neptune is almost four times as farther from the Sun than Jupiter. To put this into scale Jupiter is roughly five times further from the Sun than the Earth. Which means Neptune is almost twenty times further from the Sun than Earth is.
Neptune's orbit and Uranus' orbit are never meeting, but Pluto and Neptune do have their orbits cross. :)
