The ecliptic.
The Moon, Sun and planets all appear in a strip of sky called the ecliptic. It is a plane defined by the plane of the Earth's orbit and the Sun is always on the ecliptic, while the Moon and planets stay close to it.
The ancient Greeks called planets 'wanderers' because they appear to move through ther skies in relation to the 'fixed' stars. The apparent movement is because the planets are much closer to the Earth than the stars, and all planets rotate around the Sun, thus all move in relation to each other.
the brightest star in a constellation is called the alpha star
The belt of constellations through which all the planets move is called zodiac. The true shape of the planetary orbits was discovered by Kepler.

This is called the Retrograde

Since the visible planets as a class are the brightest things in the sky (after the Sun and Moon), the first object to appear in the evening twilight sky ... referred to historically as the "Evening Star" ... is typically a planet. It can be Mercury, Venus, Mars, Jupiter, or Saturn. However, Venus is usually referred to as the Morning and Evening star.
The Greek word planetoi means wanderer. This is why the planets in our solar system are called planets - they appear to wander about the sky relative to the fixed stars.
The brightest star in Ursa Major is a star called Alioth.
The brightest asteroid that has been discovered is called Vesta
