Definition

What Is the Neptune Entity?

Neptune (♆) is the Miscellaneous Symbols character at Unicode U+2646 (NEPTUNE). The glyph is a stylized trident for the planet Neptune (and the Roman god). Used in astronomy and astrology. HTML5 defines no named entity for it.

Remember

Character     ♆
Unicode       U+2646
Named entity  (none)
Hex entity    &#x2646;
Decimal       &#9798;
CSS escape    \2646

All of these produce the same glyph: ♆. Prefer a pasted ♆ in UTF-8 pages; use numeric or CSS forms when you need an escape.

Hex + Decimal + Direct + CSS

Four ways to produce ♆ in a single document (no named entity).

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Neptune (♆) in HTML</title>
  <style>
    #point::after {
      content: "\2646";
    }
  </style>
</head>
<body>
  <p>Using Hex Code: &#x2646;</p>
  <p>Using HTML Code: &#9798;</p>
  <p>Using Direct Character: ♆</p>
  <p id="point">Using CSS Entity: </p>
  <p>Example: ♆ Neptune</p>
</body>
</html>

Try It Yourself

How It Works

1. Hex: U+2646 → ♆ in HTML. Reliable numeric form.

2. Decimal: same code point as 9798 → ♆. Same glyph.

3. Direct: paste ♆ in a UTF-8 file with <meta charset="UTF-8">.

4. CSS: use \2646 in content (not an HTML entity). #point::after appends that ♆ after the paragraph text.

Pitfalls & Tips

Common mistakes when working with the Neptune entity.

Named

No named entity

HTML5 has no &... name for U+2646 — use hex or decimal instead.

CSS vs HTML

Do not mix escapes

\2646 belongs in CSS. ♆ / ♆ belong in HTML.

Neighbors

Not Uranus or Pluto

Uranus is U+2645; Pluto is U+2647. Neptune is U+2646.

Accessibility

Pair with text

Screen readers may not announce planet symbols clearly — add visible text (e.g. ♆ Neptune) or an accessible label when the meaning matters.

Semicolon

End references

Always finish with ; — write ♆, not &#9798.

UTF-8

Declare charset

If you paste ♆ directly, serve the page as UTF-8 with <meta charset="UTF-8">.
