This mission, launched by ESA in 1989, measured the positions and parallaxes as well as proper motions (the motion of a star on the sky observed over the years that is not caused by the parallax but reflects the actual movement of the star in space), for nearly 120,000 stars. The spa...
For nearby stars, the transverse velocities can be determined through proper motion and parallax measurements. The components of the velocity parallel to the galactic plane, and normal to the direction toward the galactic center, and the radial velocities alone. Since stars have different angular ...
vectors from the aberration of starlight and of parallax are usually presented in books on Observational Astronomy [1] in terms of scalar quantities, for which the correct interpretation of signs is not always transparent. Also, the correct deri- vation of stellar aberration is possible only ...

However, the parallax method can only be applied for stars which are reasonably close to us, since beyond distances of 1600 light years, the angles of inclination are too small to be measured by the Hipparcos satellite, a precursor to Gaia. Consequently, of the 100 billion stars in the Milk...

According to Hipparcos parallax data, Betelgeuse (HIP 27989) is 427 light-years away (give or take 92 light-years). However, the distance of Betelgeuse is still widely quoted to be between 300 and 650 light-years. Betelgeuse is one of the two stars with the largest apparent diameter (bes...
The plotted magnitudes assume that stars Band C are at the same distance as A, 100 pc, and the uncertainties in the magnitudes correspond tothe uncertainty in the Hipparcos parallax to A. Within the uncertainties, stars B and C appear tobe the same age of 2 to 8 Myr. Star A is ...
