The proper motion of a star or other object is measured by what?

The proper motion of a star or object is measured by its angular change in position on the sky over time, typically in units of arcseconds per year. This motion is caused by the true motion of the star through space, as well as the motion of Earth around the Sun.


What is the temperature of the star Mira ceti?

Mira Ceti, also known as Omicron Ceti, is a red giant star with an effective temperature of approximately 3,000 to 3,500 Kelvin. This relatively low temperature contributes to its reddish appearance. As a variable star, its brightness can change significantly over time, but its surface temperature remains within this range.
