Shirley, you can't be Sirius???
Well......the Vulcans are watching over us, from 40 Eridani. It's only about 16 1/2 LY away....
The stars in the Sirius system are rather harsh, for indigenous life. Sirius A is about twice the size of our Sun....a white-hot star, roughly
brighter than Sol!! Spectral type A1V, for Sirius A. (Sirius B is much smaller, a white dwarf....about the same diameter as
Earth, yet nearly as much mass as our own Sun!!). Sirius B is also a very strong x-ray source.
Sirius B orbits at an average of about 20 A.U., in a 49-year period.
Also, the Sirius System is estimated to be only 200 to 250 Million years old....hardly seems long enough for much biological flora and fauna to have
evolved and progressed....and, no detectable planets in the System, anyway. With its proximity (8.5 LY) should be rather more easy to spot planets,
considering how many we've discovered orbiting stars much, much farther away...
Unfortunately for the ones hoping for "aliens" from Sirius, the facts concerning the System's physical parameters are irrefutable....
The Universe is a harsh mistress........
