Explain how stars can form a constellation when seen from earth but can still be very far from each other?

It depends on what you mean by "constellation." Most people think of the word constellation as meaning the patterns made by stars in the sky (the technical term is asterism). It is possible for a star to be part of two (or more!) asterisms, and different cultures have seen different patterns. Probably the most well-known example is the Big Dipper (or Plough, or Sickle). The stars that make up the Big Dipper are a subset of the stars making up Ursa Major (the Great Bear). Another example is Andromeda and Pegasus, which at one time were considered to "share" the star Alpha Andromedae/Delta Pegasi. Officially, however, the IAU defines constellations as specific regions of the sky, sort of like how nations or states are specific regions of the Earth. It's not possible for a star to lie in two such regions at once; all the stars in the Big Dipper are in Ursa Major, and Alpha Andromedae is now considered to lie in Andromeda only.

∙ 13y agoYes. In fact, two stars that appear to be right next to each other may be hundreds or thousands of light-years apart. After all, just be sheer coincidence, there are going to be many stars that are all in the same general direction from Earth; ones that are close can appear to be on the same line of sight as ones that are very far away indeed.

∙ 12y ago- it depends if the stares are by each other and separated apart 1inch then yes it can make one straith line.
- if thers 3 stars together then it could make a triangle line.
thanx

∙ 16y agoAn interference pattern will not be generated by two close stars because 1) they are not point sources and 2) the light they emit is broadly directed and dispersed.
Wiki User
∙ 14y agoYes they can and it does happen. There is a great exchange of matter as the stars approach each other (some binary stars show this) and a huge release of energy when they collide.
Wiki User
∙ 13y agoBecause it is only the light source that is required to form a constellation or asterism.
See related link for a pictorial of the asterism Big Dipper.
Wiki User
∙ 12y agoAbsolutely not! Some may be close to us and others may be quite far away.

One day i will tell you ,my real name

What is the distance in light years of Cenaturus constellation from earth?
A constellation is basically a general direction in space. It doesn't have a definite distance. Different stars in a constellation are at different distances. The closest star from Earth happens to be in the Centaurus constellation, at a distance of about 4.2 light-years. But please note that other stars in the same constellation are much, much farther from us.A constellation is basically a general direction in space. It doesn't have a definite distance.

Is the moon a constellation?
No. A constellation is an arrangement of stars. The moon is a natural satellite of Earth.
Surface temperature of phoenix constellation stars?
A constellation is an imaginary pattern in the sky formed by imaginary lines that connect several stars. The individual stars in a constellation have no relationship or association to each other. Every star in a constellation generally has a different color, temperature, size, age, and distance from earth.
A constellation is a group of stars - pronoun?
constellation is a group of stars with a name assigned to it ;
How may ny light years is Hercules cluster away from earth?
Any constellation is a group of stars that appear to form some kind of pattern, but have no connection with each other. They all happen to be in roughly the same direction from us, but they're all at different distances. So there's no such thing as a constellation's distance from us.
Is the stars that make up a constellation are near each other?
Not necessarily. Stars within a constellation are the same general direction from Earth, but one may be much more distant than the other.

Where are the stars in a constellation located relative to each other?
Where are the stars in a constellation located relative to each other
How are stars constellation related to each other in space?
Stars in constellation can look as if they are close together, even though they are at very far distances from earth. So the stars in constellation are not, in fact, all close together. constellations are just patterns formed by stars that happen to be in the same direction of the sky.
What is a pattern of stars seen from the Earth called?
A constellation.
What is a star constellation?
A star constellation is a collection of stars that never move, unlike other stars.
What is the distance from earth and the constellation perseus?
You can't really say how far a constellation is. A constellation is just a group of stars, and even though the stars in a constellation look close together in the sky, in reality they might be very far from each other. Some of the stars could be relatively close to us, and some much farther away. Really, the only question you can answer is how far from earth is each individual star in Perseus is.
How many stars does the constellation monoceros have?
Billions or trillions of stars, just like any other constellation. A constellation is basically a general direction in space.
What does the constellation Cygnus consist of?
Stars - just like every other constellation.
What is the distance between the constellation Draco and the Earth?
All constellations are imaginary diagrams formed by patterns of many stars - each one it's own unique distance from Earth. So a constellation isn't a particular distance from Earth - as the stars only look like they're next to each other from our perspective here on Earth.
