What else can I help you with?
Does every planet have a moon?
No. Neither Mercury nor Venus have any moons.
How are all outer planets similar to each other?
All outer planets in our solar system are gas giants, made up mostly of hydrogen and helium. They have thick atmospheres and lack solid surfaces. Additionally, they all have ring systems and multiple moons.
How many jovian planets are in the solar system?
There are four Jovian planets: Jupiter, Saturn, Uranus, and Neptune.
Can you live on any of the 8 planets or their moons?
We can only know for certainty that we can live here on earth. As far as the other planets and moons, we cannot with our current technology. Perhaps sometime in the future we can either alter their climates (called planetary engineering) or design habitation modules that simulate the conditions on earth so that we can.
What are inner planet shapes?
The inner planets (Mercury, Venus, Earth, Mars) in our solar system are all roughly spherical in shape due to their gravity compressing their material into a spherical form. They lack the mass to maintain a more irregular shape like some larger moons or asteroids.
The three smallest major planets in the solar system all lack?
The smallest major planets in the solar system both lack a moon. They are Mercury and Venus. Pluto used to be a major planet and was thought to have no moon. However, it was downgraded to a dwarf planet in 2006 and has several moons.
Does every planet have a moon?
No. Neither Mercury nor Venus have any moons.
What planet has no moons?
Bothe mercury and Venus have no known moons. All of the other planets in ku solar system have at least one moon, the larger gas giant planets have many moons. It's partly due to the lack of debris in the inner part of the solar system and the fact that Venus and mercury are not very big, so can't easily capture or hold a moon.
Jovian planets lack moons?
No, they have lots of moons.
What planets lack moons?
Mercury and Venus have no moons.
What does mercury and venus lack that the outer planets have?
Moons
What characteristics do all moons share that are not shared by all planets?
All moons orbit around planets, whereas not all planets have moons. Moons are generally smaller in size compared to planets and lack an atmosphere. Moons also lack the ability to emit light on their own, unlike planets which may reflect light from the sun.
How are all outer planets similar to each other?
All outer planets in our solar system are gas giants, made up mostly of hydrogen and helium. They have thick atmospheres and lack solid surfaces. Additionally, they all have ring systems and multiple moons.
Why other planets are dangerous and earth is not?
Earth is dangerous. However there are many factors which need to be answered and lets look at our solar system first. For Humans the following factors need to be taken into account to survive without any protection Lack of Oxygen- all other planets and moons lack oxygen Lack of liquid Water- all other terrestrial planets lack liquid water (currently) however it may be present on some moons high or low temperatures (down to 3 degrees Kelvin and upwards to 700) high radiation and lack of a magnetic sphere poisonous or corrosive atmospheres Other solar systems which meet human habitation requirements might have toxic plants or biota.

Why Venus have no satellite?
Since Earth's Moon was likely formed from a chance collision, the formation of moons may not have been a stable process in the inner solar system. Any moons that formed around Venus or Mercury could have been swept away by the stronger gravity of the Sun, as might smaller moons around Earth. If Mercury or Venus ever had satellites, they were lost long ago.
