Are planets different shapes?
No. All planets are spherical.
Why are mars moons and the smaller moons of the outer planets an irregular shape while the larger moons discussed in the exploration are spherical?
Mars' moons are much smaller than, for example, Earth's Moon, or the larger moons of Jupiter. A large moon will have a larger gravity, which will tend to pull the moon together into a spherical shape.
Which Jovian Planets have no moons?
All of them 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.
What is a moon and how does it move around the solar system?
Moons are approximately spherical objects which orbit planets and are smaller than the planets that they orbit, although they are still relatively large objects (so an orbiting dust particle does not qualify as a moon). Since moons orbit planets, their motion around the solar system is controlled by the planets that they orbit; planets orbit the sun, and planets take their moons with them.
How are moons and planets alike?
Most but not all larger MOONS (bodies that orbit planets, moons, or asteroids) accreted in the same way that PLANETS did, assuming a variable density and a nearly spherical shape. Very large moons such as Titan have many of the characteristics of planets: vulcanism, atmospheres, and weather. Generally speaking, moons orbit planets in the same way that planets orbit stars.
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.
What shape do you think the universe is?
Since all of the planets, and moons, and stars seem to have a spherical shape, it is possible that the universe may be a sphere.
What shape are planet?
The inner planets have a spherical shape. In fact all planets are more or less spherical.
What is the typiccall shape of the planets?
Planets are all spherical.
Are planets different shapes?

All planets have moons?
No, Mercury and Venus do not have moons.

Do all the planets have moons traveling around them?
No, not all planets have moons. Mercury and Venus do not have any moons, while some planets like Jupiter and Saturn have a large number of moons. Earth has one moon.
