Comet (☄) is the Unicode character at U+2604 in the Miscellaneous Symbols block (official name: COMET). It is a simple astronomy / space glyph used in educational pages, labels, and light decorative UI.
Remember
Character ☄
Unicode U+2604
Hex entity ☄
Decimal ☄
Named entity (none)
CSS escape \2604
All of these produce the same glyph: ☄. Prefer a typed ☄ or hex ☄ in hand-written HTML; use decimal when generating numeric-only markup.
Comet using Hex Code: ☄
Comet using HTML Code: ☄
Comet using CSS Entity: ☄
Typed directly: ☄
How It Works
1. Hex:U+2604 → ☄ in HTML. The browser turns it into ☄.
2. Decimal: same code point as 9732 → ☄. Same result as hex.
3. CSS: use \2604 in content (not an HTML entity). #point::after appends that ☄ after the paragraph text.
4. Typed ☄: fine in UTF-8 pages. All four lines show the same glyph.
Pitfalls & Tips
Common mistakes when working with Comet entities.
Named?
No named entity
HTML5 does not define a named reference for U+2604. Use ☄ or ☄.
CSS vs HTML
Do not mix escapes
\2604 belongs in CSS. ☄ / ☄ belong in HTML.
☄ vs ☀
Different characters
☄ is U+2604. Sun ☀ is U+2600.

Do not rely on the glyph alone
Pair ☄ with text (or an accessible name) so screen-reader users get the same meaning — e.g. “Comet”.
Semicolon
End references
Always finish with ; — write ☄, not ☄.
Fonts
Coverage varies
Some fonts lack ☄. If it falls back to a box, try a font with broader Miscellaneous Symbols coverage or use SVG.
