As expected you've bollocked up the calculation; you've forgotten the contribution of the proper motion velocity components to the total velocity. The speed of sirius with respect to the solar system is about 18.2 km/sec, of which less than half is currently directed radially.

You forgot or rather ignored that everything is in orbit around something, so we're even. We are still headed towards Sirius at 7.6 km/sec and seemingly speeding up (not slowing down). ~ BG

Hardly. Why don't you work out the curvature of the trajectory of an object orbiting (essentially) the center of the galaxy at the dystance of sol and sirius? See if it makes a distance over a few thousand years. Hint: The Sun's trip around the galaxy takes about 230 to 250 million years. > > We are still headed towards Sirius at 7.6 km/sec and seemingly > speeding up (not slowing down). "Seemingly"? Where are your figures? Here are mine: It's obvious that the radial speed must increase until Sirius passes the point of closest approach in about 60,000 years, a minimum distance of about 7.8 light years, after which the radial component of the speed will decrease again. The total speed will remain at about 18.3 km/sec (vector addition of the radial and proper motion components).

C'mon junior, grow a pair and show us that you can do math. |
