What Is the Circled Asterisk Operator Entity?

Circled Asterisk Operator (⊛) is the Unicode character at U+229B in the Mathematical Operators block (official name: CIRCLED ASTERISK OPERATOR). It is used in math and logic notation when an asterisk-style operator sits inside a circle.

Remember
Character     ⊛
Unicode       U+229B
Hex entity    ⊛
Decimal       ⊛
Named entity  ⊛ / ⊛
CSS escape    \229B

All of these produce the same glyph: ⊛. Prefer ⊛ or a typed ⊛ in hand-written HTML; use numeric forms when generating markup.

Five ways to produce ⊛ in a single document.

html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Circled Asterisk Operator (⊛) in HTML</title>
  <style>
    #point::after {
      content: "\229B";
    }
  </style>
</head>
<body>
  <p>Circled Asterisk Operator using Named Entity: &oast;</p>
  <p>Circled Asterisk Operator using Hex Code: &#x229B;</p>
  <p>Circled Asterisk Operator using HTML Code: &#8859;</p>
  <p id="point">Circled Asterisk Operator using CSS Entity: </p>
  <p>Typed directly: ⊛</p>
</body>
</html>
Try It Yourself

How It Works

1. Named: &oast; (alias &circledast;) is the HTML5 named reference for U+229B → ⊛.

2. Hex: U+229B → &#x229B; in HTML. Same glyph as the named form.

3. Decimal: same code point as 8859 → &#8859;. Same result as hex.

4. CSS: use \229B in content (not an HTML entity). #point::after appends that ⊛ after the paragraph text.

5. Typed ⊛: fine in UTF-8 pages. All five lines show the same glyph.

Pitfalls & Tips

Common mistakes when working with Circled Asterisk Operator entities.

Named

Use &oast;

&oast; and &circledast; both work. Always end with ;.

CSS vs HTML

Do not mix escapes

\229B belongs in CSS. &oast; / &#x229B; / &#8859; belong in HTML.

⊛ vs ⊗

Different characters

⊛ is U+229B. Circled times ⊗ is U+2297.

Meaning

Math operator, not footnote

Use ⊛ for formal notation. Use * for footnotes, wildcards, or casual emphasis.

Semicolon

End references

Always finish with ; — write &oast; and &#8859;, not bare forms.

Fonts

Math font coverage

Some UI fonts lack ⊛. If missing, label the operator in nearby text.

Browser Support

Circled Asterisk Operator (U+229B) and its entity forms (&oast;, &circledast;, &#x229B;, &#8859;, CSS \\229B) are supported in all mainstream browsers.

✓ Universal support

Circled Asterisk Operator (⊛)

Type ⊛, or encode with named, hex, decimal, or CSS escape — same glyph everywhere encoding is supported.

Bottom line: Prefer &oast; or a typed ⊛ for math notation. Use decimal when generating markup, and \\229B only inside CSS content.

Key Takeaways

  • Unicode: circled asterisk operator is U+229B (decimal 8859).
  • HTML: prefer &oast; (also &circledast;, &#x229B;, &#8859;).
  • CSS: use \229B inside content for generated text.
  • Watch out: ⊛ ≠ ⊗ (circled asterisk ≠ circled times).

One line: U+229B → &oast; / &#x229B; / &#8859; / CSS \229B.

Frequently Asked Questions

Use &#x229B; (hex), &#8859; (decimal), &oast; or &circledast; (named), or the CSS escape \229B in the content property. All render ⊛. You can also paste ⊛ directly when your file is UTF-8.
U+229B (hex 229B, decimal 8859). Unicode names it CIRCLED ASTERISK OPERATOR. It belongs to the Mathematical Operators block.
Yes. Both &oast; and &circledast; map to U+229B. Prefer &oast; in hand-written HTML; numeric forms are useful in generated markup.
⊛ (U+229B) is circled asterisk operator. ⊗ (U+2297) is circled times — a different math operator with its own code point.
HTML entities (&#8859;, &#x229B;, &oast;, or &circledast;) go in markup. The CSS escape \229B is used in stylesheets (usually in the content property of ::before/::after). Both render ⊛.
Use it in math, logic, or scientific notation when you need this exact operator. Prefer a plain asterisk (*) for everyday footnotes or emphasis.

Did you know?

Circled asterisk operator is Unicode U+229B (decimal 8859) — official name CIRCLED ASTERISK OPERATOR in the Mathematical Operators block. HTML named references are &oast; and &circledast;. It is not circled times (U+2297 ⊗).
