Struktur [[matahari]], sebuah bintang tipe G: {{div col|colwidth=30em}}{{ordered list
'''Bintik matahari''' adalah bagian dari permukaan [[matahari]] ([[fotosfer]]) yang dipengaruhi aktivitas magnetis hebat, yang mengakibatkan konveksi terhambat, membentuk daerah bersuhu lebih dingin. Bintik-bintik ini bisa terlihat dari bumi tanpa bantuan [[teleskop]]. Meski bersuhu sekitar 4000-5000K, perbedaan dengan materi sekelilingnya yang berkisar sekitar 5800K mengakibatkan daerah ini tampak secara jelas sebagai noda-noda hitam karena intensitas sebuah [[benda hitam]] yang dipanasi adalah sama dengan T (temperatur) berpangkat empat. Jika sebuah bintik matahari diisolir dari fotosfer sekelilingnya ia akan tampak lebih cemerlang dari loncatan bunga api listrik. ▼
