Mercury, the smallest and innermost planet, has no moons, or at least none that can be detected to a diameter of 1.6 km (1.0 mi). [2] For a very short time in 1974, Mercury was thought to have a moon. Venus also has no moons, [3] though reports of a moon around Venus have circulated since the 17th century.
The other moons are Europa (further right), Io (first on left), and Callisto (furthest on left). Photo taken with Nikon P900 on 24 July 2020, ten days after opposition . Solar eclipses on Jupiter occur when any of the natural satellites of Jupiter pass in front of the Sun as seen from the planet Jupiter.
According to NASA, after the total solar eclipse on April 8, 2024, the next total solar eclipse that can be seen from the contiguous U.S. will be on Aug. 23, 2044. What does a solar eclipse look ...
Of the inner planets, Mercury and Venus have no natural satellites; Earth has one large natural satellite, known as the Moon; and Mars has two tiny natural satellites, Phobos and Deimos. The giant planets have extensive systems of natural satellites, including half a dozen comparable in size to Earth's Moon: the four Galilean moons , Saturn's ...

NASA's Galileo ' s measurements suggest that large moons can have magnetic fields; it found Ganymede has its own magnetosphere, even though its mass is only 2.5% of Earth's. [18] Alternatively, the moon's atmosphere may be constantly replenished by gases from subsurface sources, as thought by some scientists to be the case with Titan.
A total solar eclipse happens when the moon passes between the sun and earth to completely block the face of the sun, the folks at NASA explain. The sky then darkens as if it were dawn or dusk.
