star
Any small, natural and bright dot in the sky, most visible in the night or twilight sky. This sense includes the planets, but it is now sometimes used in exclusion of them due to influence from the technical astronomical sense.
Example
“He loved watching the stars in the sky with her.”
Other meanings
A planet thought to influence one's fate; (figuratively) fate or luck.
A very massive ball of plasma with strong enough gravity to have ongoing fusion of hydrogen or heavier elements in its core. In strict technical usage, the Sun is included.
