Ursa Major is primarily known from the asterism of its main seven stars, which has been called the "Big Dipper," "the Wagon," "Charles's Wain," or "the Plough," among other names. In particular, the Big Dipper's stellar configuration mimics the shape of the "Little Dipper." Two of its stars, named Dubhe and Merak (α Ursae Majoris and β Ursae Majoris), can be used as the navigational pointer towards the place of the current northern pole star, Polaris in Ursa Minor.

Asteroids: These are the rocky and airless leftovers from the formation of planets in our solar system. They mostly orbit our sun in the asteroid belt between Mars and Jupiter and range from the size of cars to dwarf planets.

Comets: Comets are dirty space snowballs of mostly ice and dust that formed during the birth of the solar system 4.6 billion years ago. Most comets have stable orbits in the outer reaches of the solar system past the planet Neptune.

Meteoroids, Meteors, Meteorites: Meteoroids are tiny asteroids or the broken-off crumbs of comets and sometimes planets. They range in size from a grain of sand to boulders 3 feet (1 meter) wide. When meteoroids collide with a planet's atmosphere, they become meteors. If those meteors survive the atmosphere and hit the planet's surface, their remains are called meteorites.
