Which planet or moon is more suitable for the evolution of higher life?

Now that you've said your premise that both environments are suitable for the evolution of complex life, then I can responsibly tell you that in this case, moons and planets are equally suitable for the evolution of life. In response to your three questions, I will go one by one:

1. The length of the night is not the decisive factor affecting the evolution of life, you say that you may not be adapted to being blocked by the planets, it is because you live on the earth, and if you live on the moon, you may not adapt to the earth. Not to mention that planets can also be blocked by moons, such as the Tengu Eclipse (the moon blocks the sun's rays). Moreover, the length of day and night is mainly determined by the rotation speed of celestial bodies, and many satellites rotate faster than planets.

2. Celestial bodies may be attacked by foreign celestial bodies. If the alien body is big enough, then you are in a tragedy whether you live on a planet or a moon. If the celestial body is relatively small, it can rely on the friction of the atmosphere to eliminate foreign objects, since you say that the environment of both is suitable for the evolution of complex life, then it means that both have the same atmosphere, that is, both can test the atmosphere to consume small extraterrestrial visitors.

If you say that the planet has its own moons to help it keep out visitors from the sky, then I tell you, this is impossible, because the planet's moons are small and do not have the ability to clear orbits. So, at this point, planets also don't have a clear advantage over satellites. Both environments are suitable for the evolution of complex life.

3. If the phenomena described in Article 3 exist, it means that the moon is too close to the gas planet around it, in which case the premise on which you ask these questions is no longer there.

Jupiter. Jupiter has at least 79 moons.

Jupiter is the largest and fastest rotating planet among the eight planets in the solar system, the fifth planet from the inside out. It has a mass of one-thousandth the mass of the Sun and a mass of the other seven planets in the Solar System combined. Since Jupiter, Saturn, Uranus, and Neptune are all gas planets, they are also called Jupiter-like planets (Jupiter and Saturn are collectively called gas giants).

Jupiter appears as an oblate sphere (a slight but noticeable bulge near the equator) due to its rapid rotation (9 Earth hours per rotation). The outer atmosphere is clearly divided into multiple zones according to latitude, and the margins where each zone is connected are prone to turbulence and storms, the most obvious example of which is the Great Red Spot. The planets are surrounded by a weak system of planetary rings and a powerful magnetosphere (Jupiter's magnetic field is so strong that it extends to Saturn's orbit with its back to the Sun).

Jupiter has at least 79 moons.

Ingredients. Jupiter's upper atmosphere is made up of about 88-92% hydrogen and about 8-12% helium in volume or gas molecules. Since the mass of the helium atom is four times that of the hydrogen atom, the mass composition of Jupiter changes somewhat:

Hydrogen and helium make up 75% and 24% of the total mass respectively, and the remaining 1% is made up of other elements, including trace amounts of methane, water vapor, ammonia and silicon. In addition, Jupiter also contains trace amounts of carbon, ethane, hydrogen sulfide, neon, oxygen, phosphine in the empty zone, sulfur and other substances. The outermost layer of the atmosphere contains frozen ammonia crystals.

Trace amounts of benzene and hydrocarbons have also been detected on Jupiter through infrared and ultraviolet measurements.

The ratio of hydrogen and helium in Jupiter's atmosphere is very close to the theoretical composition of the original solar nebula, however, Jupiter's atmosphere contains two to three times as much noble gas as the Sun, neon in the upper atmosphere accounts for only twenty parts per million of the total mass, about one-tenth of the proportion of the Sun, and helium is almost depleted, but there is still 80% of the proportion of helium in the Sun. This gap may be due to the precipitation of elements into the interior of the planet.

The planet with the most moons in the solar system has been found to be Jupiter, which has 79 moons.

Jupiter. As of August 2019, astronomers have confirmed 10 new moons orbiting Jupiter, bringing the planet's total known to 79 moons. This is what makes Jupiter the planet with the most natural satellites in the solar system.

Astronomers at the Carnegie Institution for Science first discovered the moons in March 2017, along with two more that were already identified last June. The team initially used Chile's Blanco 4-meter telescope to discover all 12 satellites, but found that the objects were not their main targets. Instead, they are looking for extremely distant small objects – or even planets – that may be lurking outside of Pluto.

But when they searched for these marginal space rocks, they decided to search for the celestial bodies lurking around Jupiter at the same time. Now the satellites they discovered have been observed several times, and their exact orbits have been submitted to the International Astronomical Union for approval, which officially recognizes these objects.

The planet with the most moons in the solar system is Jupiter, with 79 moons currently discovered. Jupiter's total mass is very large, so it attracts many observable planets, and the four most famous moons were discovered by the famous astronomer Galileo, so they are also called Galilean moons.

Jupiter is a gas giant, Saturn, Uranus, and Neptune are all gas planets, and the surface is composed of large modulus gases, and the four planets are also called Jupiter-like.

Jupiter is the fastest rotating and largest planet among the eight planets in the solar system, with a mass of one-thousandth the Sun, making it the fifth closest planet to the Sun.

Originally, Jupiter was named after the main god Jupiter by the Romans, and in ancient China it was called the Year Star.
