Oh, dude, the period of a planet is just how long it takes to orbit the sun once. So, for a planet with a solar distance of 10 astronomical units (AU), you can use Kepler's third law to calculate the period. It's like doing the math homework you never wanted to do in high school, but hey, at least you'll know how long that planet takes to make a full lap around the sun!
Venus is the only inner solar system planet whose day (rotation period) is longer than its year (orbital period). Venus takes about 243 Earth days to rotate once on its axis (solar day) and approximately 225 Earth days to complete one orbit around the Sun (solar year).
The planet that has 9 letters in its name is "Neptune." Neptune is the eighth and farthest known planet from the sun in our solar system. It is a gas giant with a blue color due to the presence of methane in its atmosphere.
None in our Solar System. Outside of it, there are a bunch of planets whose name starts with "K2", or with "Kepler", or with "KELT". Check the Wikipedia article "List of exoplanets (full)" for the complete list.
The gas planets are any of the four large outer planets of the Solar System, Jupiter, Saturn, Uranus and Neptune, which consist largely of gas and whose visible surfaces are not solid, though they have solid cores.
The planet with the greatest eccentricity in our solar system is Mercury. eccentricity refers to how much an orbit deviates from a perfect circle, and Mercury's orbit is the most elongated and eccentric of all the planets.
Not in our solar system there isn't.
Venus is the only inner solar system planet whose day (rotation period) is longer than its year (orbital period). Venus takes about 243 Earth days to rotate once on its axis (solar day) and approximately 225 Earth days to complete one orbit around the Sun (solar year).

Jupiter. Its weight is roughly 2.5 times the size of all the other planets in our solar system combined.
'Earth' - English word meaning good old terra firma.
There is no such planet known. In our solar system, the planet whose moon is closest in size to the planet which it orbits is none other than our own planet Earth. However, the Moon is still much smaller than the Earth. Pluto has a Moon that's big, but Pluto isn't a "planet" now, of course.

Going outwards from the Sun, the next planet in the solar system after Earth would be Mars. Going inwards from Earth towards the Sun, the next planet is Venus - whose orbit is actually closer to Earth's than that of Mars.
Formerly than answer was Pluto, whose moon Charon is just over half its diameter. Now that Pluto is technically not a planet, than answer is Earth, whose moon is just over a quarter its diameter.

No planet has been discovered yet whose average distance from the sunis smaller than that of Mercury.Mercury and Venus both orbit closer to the sun than Earth does.
