Roughly speaking, a constellation is a direction in the sky. The introductory paragraph of the Wikipedia summarizes the concept quite well: 'In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around patterns that represent the shapes that give the name to the constellations. When astronomers say an object is "in" a given constellation, they mean it is within the boundaries of one of these defined areas of sky, as the patterns may have several variants in its representation.'
In modern astronomy, there are 88 or 89 constellations, depending on how you count.
There are many popular constellations that are visible from Canada. Popular constellations include the big and little dipper for example.
There are 88 officially recognized constellations.
A star cluster, or, perhaps, a local group might be used to describe a "closely associated" number of stars which are part of a larger stellar group, like a galactic arm or the like. D. Galaxy
These are different questions. The constellations were created from the imaginations of the people who observed the stars. Most of our "standard" northern hemisphere constellations were from Greek or Roman mythology. Many of the southern hemisphere constellations were named by European sailors and navigators as they first sailed into southern waters. Note the nautical themed constellation names like "Sextans" and "Telescopium" and "Cetus", the whale. The International Astronomical Union standardized all of the constellations, and assigned every visible star to one, and ONLY one, constellation.
There is almost certainly no record of this. The Big Dipper is part of Ursa Major and the Little Dipper is Ursa Minor. Given the latin names and the fact that both are easily visible with the naked eye means that they would have been discovered millenia ago.
No - not necessarily. There are many constellations that almost completely cover the sky, however some stars fall in between many of the figures that make up the constellations.
One.Orion doesn't "have constellations". Orion is a constellation.
Aires is a constellation
There are 88 constellations.
It is possible for new constellations to form. Stars are born every day, however, it will take many years to form the constellation.
Conservatively, trillions, as with all constellations.
That doesn't make sense. A constellation is basically a direction in space; you don't count constellations per galaxy or similar regions in space. There are 88 or 89 constellations (depending how you count them); these constellations cover all the directions around us, and are not related to any specific galaxy.

There are over 88 listed Constellations - too many to name here.
I can find no trace of Leonardo finding any constellation.
I gazed up into the night sky and marveled at the many constellations.
There are a total of 88 constellations in the sky, but many of them are visible from only the southern hemisphere
