Towards Earth, at 7.6 km/sec. They say that in the future, we might be in "Sirius" trouble - but the fact is that Sirius doesn't move exactly towards Earth; there is also a sideways movement, so Sirius would miss us.
What else can I help you with?
How did astronomers discover that the star Sirius was moving away from earth?
They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
What did the astronomers use to discover that the star Sirius was moving away from Earth?
A freaking telescope
How fast is Sirius moving away from Earth in miles per second?
26 tO 36 mps
How does the Doppler shift determine the distance of Sirius?
It doesn't. The Doppler shift can tell you how fast something is moving towards us or away from us; not how far it is. Only in the case of distant galaxies can this be used to estimate the galaxy's distance, because of the expansion of the Universe (galaxies that move away from us faster are generally farther away).
Is the moon falling towards the earth?
No, the moon is not falling towards the Earth. It is actually moving away from our planet at a very slow rate.
Why is the Andromeda galaxy moving toward earth?
Sorry, Andromeda and earth are moving away from each other, not towards each other.
Does the velocity of a star toward or away from earth determine measuring the shift of its spectral lines?
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
How many miles is it from Earth to the star Sirius?
Sirius is about 8.6 light years away which works out to about 50,600,000,000,000 (50.6 trillion) miles away.
How do you use spectral lines to determine if a galaxy is moving towards earth or away from earth?
The spectral lines move towards one direction, or towards the other direction, depending on the relative speed.
How much larger is capella than Sirius?
Capella is about 42.2 light-years away from Earth, while Sirius is about 8.6 light-years away. Therefore, Capella is approximately 4.9 times larger in terms of distance from Earth than Sirius.
How much farther is canopus from earth than sirius?
These are the 2 brightest stars in the sky. However Canopus is a lot more luminous because it is much further away. Canopus is about 310 light years away. Sirius is only 8.6 light years away.
Why does it get colder as you move upwards?
Because you are moving away from the hot equator. You are going towards the ice caps of Earth.
