There are currently 88 officially recognized constellations.
Draco is a constellation in the far northern sky. Its name is Latin for dragon. Draco is circumpolar (that is, never setting) for many observers in the northern hemisphere. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations today.Source: Wikipedia.
All of them. Constellations that are very far north or south, such as the Little Dipper, will be very low on the horizon, but you should be able to see them if you are on a tall building or on a hillside.
To the nearest Star
Constellations appear to form images in the night sky, but each of the stars are extremely far away fron each other. They just line up from our own viewing points.
Parallax is the apparent change in postion of an object when looked at from two different places. Astronomers use parallax to find how far away nearby stars are.
Some of them, yes. Constellations along the Zodiac can be seen from either hemisphere, but constellations well away from the celesial equator cannot be seen very far in the other hemisphere. For example, Ursa Major is not visible in Australia, and the Southern Cross is not visible in Europe or North America. Most of the "official" constellations were named by northern hemisphere astronomers, or European navigators sailing in southern waters. Look at how many southern hemisphere constellations have a nautical theme; the Telescope, the Octant, the Quadrant. Even Cetus, the Whale, was named by sailors, not people who LIVED there.
No. There are some that don't exist as far as we know!
1. Every visible star in the sky is part of a constellation. 2. A pattern in the sky that is widely recognized but not an official constellation is called an asterism. Ex. The Big Dipper or the Plough. 3. Many of the stars that make up constellations are extremely far apart but only appear to be close together.There are 88 named constellations.The Plough is part of the Ursa Major.The Constellation Sexans the Sextant is a Modern Creation.There are twelve constellations in the Zodiac.The Pole Star is in Ursa Minor.

Hubble was a legend among astronomers, for many reason, but his most noteworthy achievement was probably the discovery and subsequent proof that what were called at that time "nebulae", were actually separate galaxies like our own, and hence very far away from us. That one discovery kind of took astronomy from "high school" to "college"

There are far more than two constellations.The IAU (international Astronomical Union) recognises 88
Constellations are made of stars, and there are no stars in between Earth and Jupiter. There is only one star in our solar system, and that is the Sun. All others are very, very, very, very far away.
