What else can I help you with?
Why do planets closer to the sun have a shorter year?
Their orbit is a smaller circle than the ones further out, and as long as they are moving at relatively the same speed they will complete each orbit faster. Check out the planetary orbits link, it gives a really cool description and moving diagram
How does red shift differ between galaxies close to us and ones which are further away?
Generally, the galaxies that are further away will have the larger red shifts.
What planets have a longer revolutions?
The ones that are farther from the sun have longer revolutions.
At least how many galaxies are located within the Draco constellation?
The Draco constellation contains at least 30 recognized galaxies, including notable ones like the Draco I and Draco II dwarf galaxies. Additionally, there are several other smaller galaxies and galaxy clusters within its boundaries. The exact number may vary as new discoveries are made and classifications change.
At least How many galaxies are located with the Draco constellation?
The Draco constellation contains several galaxies, with at least 20 notable ones identified, including the well-known spiral galaxy NGC 5866 and the elliptical galaxy NGC 6285. Additionally, there are numerous smaller dwarf galaxies associated with Draco, such as the Draco I and Draco II dwarf spheroidal galaxies. While the exact number of galaxies may vary as new discoveries are made, Draco is home to a rich variety of galactic structures.
How did Edwin hubble determine that the universe must be expanding?
The red shift. A Doppler effect (used in speed trap radar) showing that all (except for a few close ones) galaxies are moving away from us - and the farther away they were the faster they were moving.
What galaxies in the universe are irregular galaxies?
Irregular ones!
What other galaxies do you have in your universe?
There are billions of other galaxies; perhaps 100 billion or so (1011) in the observable Universe. Some of the closer ones - that can be seen with the naked eye - are M31 (a.k.a. the "Andromeda Galaxy", the Large Magellanic Cloud, and the Small Magellanic Cloud.
Why isn't a galaxys size alone useful in determining its distance from Earth?
The only thing that can be directly observed is a galaxy's apparent size (angular size). Since galaxies come in different sizes, this can only give a rough idea of the galaxy's distance from Earth.
Do planets orbit fast or slow if so which ones?
The close-in ones move fast, the far-out ones move slower. It's governed by Kepler's third law.
What galaxies can you see?
The closest ones near our galaxy.
Why do planets closer to the sun have a shorter year?
Their orbit is a smaller circle than the ones further out, and as long as they are moving at relatively the same speed they will complete each orbit faster. Check out the planetary orbits link, it gives a really cool description and moving diagram
What unit of measure is most often used to describe distances to other stars beyond the sun?
-- "Light Year" for the closer ones -- "Parsec" for the farther ones
What galaxies are elliptical?
They look like eclipse ones like s82o.
How does red shift differ between galaxies close to us and ones which are further away?
Generally, the galaxies that are further away will have the larger red shifts.
Do Giant Supernovas create super massive black holes?
No, only small ones, the supermassive ones are at the centre of galaxies.
How old are the stars in spiral galaxies?
A spiral galaxy is just a type of galaxy but I can tell you that the stars in the middle are the oldest and the ones on the outside are the youngest.
