Daftar bintang terbesar

artikel daftar Wikimedia

Di bawah ini adalah daftar bintang terbesar yang diketahui saat ini, diurutkan berdasarkan radius. Satuan pengukuran yang digunakan adalah jari-jari Matahari (kira-kira 695.700 km; 432.288 mi).

Ukuran relatif planet di Tata Surya dan beberapa bintang terkenal:

Ketidakpastian besar tetap ada pada keanggotaan dan urutan daftar, terutama ketika mendapatkan berbagai parameter yang digunakan dalam penghitungan, seperti bintang luminositas dan suhu efektif. Seringkali jari-jari bintang hanya dapat dinyatakan sebagai rata-rata atau dalam rentang nilai yang besar. Nilai untuk radius bintang sangat bervariasi di berbagai sumber dan untuk metode observasi yang berbeda.

Diameter sudut banyak bintang dapat diukur secara langsung menggunakan interferometri bintang. Metode lain dapat menggunakan okultasi bulan atau dari biner gerhana, yang dapat digunakan untuk menguji metode tidak langsung untuk menemukan jari-jari bintang. Hanya beberapa bintang supergiant berguna yang dapat disembunyikan oleh Bulan, termasuk Antares A (Alpha Scorpii A). Contoh biner gerhana adalah Epsilon Aurigae (Almaaz), VV Cephei, dan V766 Centauri (HR 5171). Pengukuran diameter sudut bisa jadi tidak konsisten karena batas atmosfer yang sangat tipis (opasitas) berbeda-beda bergantung pada panjang gelombang cahaya di mana bintang diamati.
