The stars in a constellation appear to be in the same plane because we are viewing them from very, very, far away. Stars vary greatly in size, distance from Earth, and temperature. Dimmer stars may be smaller, farther away, or cooler than brighter stars.

Why do constellations not change?
The stars are not fixed, but are constantly moving. If you factor out the daily arcing motion of the stars across the sky due to the earth's rotation, you end up with a pattern of stars that seems to never change.
Why do we see the same constellations all year?
Earth's axis remains pointing in the direction of Polaris (the North Star) for the entire year. In the northern hemisphere (above the equator) we can see the stars and constellations near Polaris (like the Big Dipper and Cassiopeia) that seem to rotate around it nightly, all year long.
Will constellations change over time?
Seeing constellations change over time. ... Due to the action of stellar proper motion over millennia, the constellations we see today are altered from the star patterns that the Babylonians saw. In most cases, the changes are barely noticeable, but a few are readily apparent.
How are constellations in the same place?
Why? Yes, stars and constellations appear in the same place in the sky every night. This is because the Earth is moving so it looks like the stars and constellations are moving, but actually, we are!
What happens if a star in a constellation dies?
Stars die because they exhaust their nuclear fuel. ... Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a 'supernova'.
Are there any constellations that no longer exist?
Argo Navis is the only constellation from Ptolemy's original list of 48 constellations that is no longer officially recognized. Due to its large size, it was split into three constellations by Nicolas Louis de Lacaille: Carina (the keel), Puppis (the poop deck), and Vela (the sails).
Did you see same constellation every time you move your head why?
You always see the same half of the celestial sphere, completely distinct from the half that you would see from earth's north pole. The explanation for all these effects is simply that the earth's surface is curved. So when you travel to a different location, your horizon tilts with respect to the stars.
Does everyone see the same constellations?
Not everyone has the same set of stars in their back yard. The constellations appear in different positions throughout the seasons, disappearing and reappearing, depending on where you live in the world.
Why do the star patterns change at different times of the year?
Correct answer:
Different seasons bring different constellations. Explanation: The Earth completes its orbit around the Sun or its revolution in about 365 days total. As the Earth revolves around the Sun, the position of the Earth changes, and this creates the different views of the night sky.
Did the Big Dipper lose a star?
And that's why – millions of years from now – the Big Dipper will have lost its familiar dipper-like shape. Astronomers have found that the stars of the Big Dipper (excepting the pointer star Dubhe and the handle star Alkaid) belong to an association of stars known as the Ursa Major Moving Cluster.
Will the Big Dipper ever disappear?
Like all stars in the sky, their position in the sky changes over time. This is called proper motion, and it will ultimately distort the “big dipper” until it will become unrecognizable in several tens of thousand of years.
What do the French call the Big Dipper?
"Ah, yes! We call that the Big Dipper ..." "La Grande Ourse...
What stars stay in the same place?
The North Star, also known as Polaris, appears to stay in the same place constantly, even during the day. However, it, like everything else in the universe is moving. Yet, Polaris happens to be very close to being in-line with the spin axis of the Earth.
Why do you think the people living in the northern hemisphere see constellations differently compared to those living in the southern hemisphere?
In other words, if you live in the Northern Hemisphere, you can see all of the constellations on the northern part of the sky, and maybe some of what is visible from the Southern Hemisphere. ... Since the sun only shines for about half the day, you lose sight of constellations blocked by sunlight.
Do stars stay in the same place all night?
The stars are NOT in the same location in the sky. Just like the moon and sun they appear in different places every minute of time.
How are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. ... Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud collapses, the material at the center begins to heat up.
Why can't I see the stars at night anymore?
Nowadays, we cannot see the stars because of light pollution. It is a kind of pollution caused due to use of artificial lights at night. Mainly misdirected light is the main cause. As this light spreads in the atmosphere at night, it alters the natural level of light.
