Backyard View of Sky Around HD 140283

Oldest Star in Solar Neighborhood

This is a Digitized Sky Survey image of the oldest star with a well-determined age in our galaxy. The aging star, cataloged as HD 140283, lies 190.1 light-years away. Hubble Space Telescope was used to narrow the measurement uncertainty on the star's distance, and this helped...

Stellar Parallax

Distances to stars comparatively near to our Sun can be measured using trigonometric parallax. This can only be done if the star is close enough to show an apparent shift in position relative to much farther background stars, as seen at upper right. This requires viewing the...
