According to the geophysical planet definition, what makes a planet a planet is that it is a non-self-luminous celestial spheroidal body orbiting a star, free floating in space, or even orbiting another planet. In other words, what makes a planet a planet are its intrinsic characteristics.If an object is not a star and is large enough for its gravity to squeeze it into a round or nearly round shape, it is a planet.

Skeletal muscle is striated muscle tissue that is attached to bones. It is composed of fibers that look like a mixture of dark and light bands bundled together that run along the bone.here are three different types of muscle tissue within the body. Skeletal muscle is striated muscle tissue that is attached to bones. Skeletal muscle attaches to the bones. At the macroscopic level, the skeletal muscles are composed of a variety of layers.
Humans have three different kinds of muscle: 1  Skeletal muscle is attached to bone, mostly in the legs, arms, abdomen, chest, neck, and face. Skeletal muscles are called striated because they are made up of fibers that have horizontal stripes when viewed under a microscope. These muscles hold the skeleton together, give the body shape, and help it with everyday movements (known as voluntary muscles because you can control their movement). They can contract (shorten or tighten) quickly and powerfully, but they tire easily and have to rest between workouts.
