47 Ursae Majoris is about 46 light years away.
Ursa Minor or "The Little Bear" is a constellation. It is made up of many stars, each one having it's own unique distance from Earth. It only looks like Ursa Minor from our perspective.

Ursa Major is a constellation, made up of many different stars. "It" doesn't have a temperature. Each star in it has it's own temperature.
There are 88 recognized constellations in total, and around 15 of them are named after animals. These include constellations like Leo (the Lion), Ursa Major (the Great Bear), and Taurus (the Bull).
The constellation Ursa Major contains about seven main stars that form the shape of a bear. The most famous of these stars is the Big Dipper or Plough asterism, which is not a constellation in itself but part of Ursa Major.
There are no planets in the constellation Ursa Major. This constellation is home to many stars, including the well-known star cluster known as the Big Dipper or the Plough. However, planets in our solar system can be seen passing through or near Ursa Major at different times due to their orbits.
Ursa Major means "Big Bear" Ursa means Bear, and Major means large. Ursa Minor means Ursa as in Bear and minor as in small. These names either came from the Greeks. In the U.S.A., Ursa Minor and Ursa Major are Little Dipper and Big Dipper.The Greeks looked at the two and said, "Those stars look like a little bear and a big bear" That's how Ursa Major and Ursa Minor got there name. Now, people in the U.S.A. thought that the Ursa Major and Ursa Minor looked like dippers. Scientists call them Ursa Major and Ursa Minor, I personally call them Ursa Major and Ursa Minor, but some children and adults call them Little Dipper and Big Dipper and that's how they got there name.Who discovered the Ursa Major?AnswerThe Ursa Major was known to astronomers before the medieval period,therefore the exact person is unknown.This is known as the ancient Indians called it "The Saptarishi"(Seven Saints,namely Kritu,Pulah,Pulatsya,Atri,Angira,Vashishtha,and Mareech)and believed that the sages had been grouped together.
The Big Dipper is not a single object, but an asterism or pattern of stars in the constellation Ursa Major. The stars in the Big Dipper are at different distances from Earth, so it doesn't have a specific size in terms of light years across.
The question is vague. There are many stars called "pointer" stars. For example, two of the stars in Ursa Major lie along a line that passes very near Polaris. A completely different set of stars in Ursa Major form an arc that passes near Regulus. There are plenty of other such astronomical coincidences.
Trillions, or more than that: Any star that is in the same general direction is considered to be in that constellation.
They are 3 different constellations. So they look different, have different stars, are in different parts of the sky, are seen at different times. There are many other differences too.
The Ursa Major constellation contains around seven main stars that form the well-known asterism called the Big Dipper or Plough. Each of these stars has its own individual name, such as Dubhe, Merak, and Alkaid.
