Two
further small moons, Nix and Hydra, were found by Hubble in 2005.

The end result is a neatly ordered satellite system, with
small moons on the inside built from few moonlets and large
moons farther out built from numerous moonlets.
The simulation suggests rocks on the
far side come mostly from the
smaller moon, which should have previously cooled and solidified faster than the main
moon, making its rocks older.
The intense geological activity is the result of heat produced by a gravitational tug - of - war between Jupiter's massive gravity and other
smaller but precisely timed pulls from Europa, a neighboring
moon to Io that orbits
further from Jupiter.
Scientists long thought that the A ring, which orbits
further out, was hemmed in the same way by the
smaller moon Janus.
So
far, the search has not identified any dangerous dust bands around Pluto, but it has turned up two newfound
moons — a
small object called P4 last year, and now P5.
It also offers among others an answer to the long - standing question of where the energy that can support water in liquid form on the
small, cryovulcanic
moon far from the sun comes from.
It's a solar eclipse, with the
Moon blocking the Sun, but because the
Moon is at apogee — the point in its orbit
farthest from Earth — the
Moon appears
smaller in the sky, so it doesn't completely block the Sun.
Forming stars, planets,
moons, or meteoroids by capturing18
smaller orbiting bodies is
far more difficult than most people realize.19 However, if gases are inside these spheres, capture becomes more likely, and the more particles captured, the larger the sphere of influence becomes.
As it happens, the Sun and
moon appear about the same size in the sky, with the
moon appearing larger when it's closest to Earth and slightly
smaller when at the
farthest point in its orbit.
Janus (179 km across) is on the
far left, Pandora (81 km across) orbits between the A ring and the thin F ring, Enceladus (504 km across) is centre, Rhea (1,528 km), is bisected by the right edge of the image and the
smaller moon Mimas (396 km) is seen beyond Rhea also on the right side of the image.
So for her first three years on the job, Jackman used computers to model the exact location of the center of the Pluto system (which includes one large
moon and four
far smaller ones in addition to Pluto).
This unexpected finding of an ocean on a
small moon so
far from the Sun raises a distinct possibility: that there are more oceans on more
moons, each with a chance for life.
Enceladus is roughly the diameter of England — relatively runty for a
moon and
far too
small to hold onto the primordial heat left over from its formation.»
With a diameter of 2,370 km it's
far smaller than even our own
Moon.
Named by Algonquin tribes as the «Strawberry
Moon» for a time of ripening fruit, the June full moon is also being called a «mini-moon» (or apogee moon) since it's the smallest full moon of 2017 at its furthest point away from Earth — making it the opposite of a superm

Jupiter is 25,000 heavier than the
Moon, but is 2000 times
further away, so the tides are 25,000 / 2000 ^ 3 = 0.000,003 times that of the
Moon [that is 300,000 times
smaller], completely negligible.
So that's why Juno's camera has a field of view about 130 times wider than Voyager, and thus why Eath seems so much
smaller even though Voyager was a little
farther away when it took its Earth -
moon image.»
In particular; although the
Moon is
far less geologically active than the Earth, it does have considerable internal heat and there is a
small flux of heat going up towards the surface.
