A small disc trailing a set of diverging lines.
Also known as: Comet
A body with a bright head and a tail streaming away from the Sun. Used in almanacs to mark a comet's appearance and, more loosely, for anything sudden and streaking.
Marks a comet — an icy body whose approach to the Sun produces a bright head and a tail pointing away from it.
Encoded at U+2604 in the Unicode Miscellaneous Symbols block.
The tail points away from the Sun rather than backwards along the path, so a comet moving away from the Sun travels tail-first — which most drawings of comets get wrong.
A small filled circle with three or more straight lines streaming away from it and spreading apart as they go.
Both belong to the set of astronomical symbols used in almanacs and charts.
