<p><b>食分</b>（英語：magnitude of eclipse，或簡稱 magnitude）是被食天體在食的過程中變暗淡部分在直徑上的分數，這對日食和月食都適用。在偏食和環食，食分永遠介於0.0和1.0之間，而全食時至少是1.0。 </p><p>從技術面看，食分是這樣計算的：畫一條直線連接食的天體（或本影）和被食天體的中心，找出這條線有多少部分在被食天體被食的部分；這是幾何學上的食分。如果是全食，這條線必須延伸至致食天體（或陰影）最靠近一側的邊緣，並且得到大於1.0的食分。如果沒有食，但是接近失誤，也可以將這條線延伸至最靠近的邊緣，並以負值計算這個距離，得到一個負的幾何學食分。 </p><p>在英文，食分和星等是同一個字：<span lang="en">Magnitude</span>，因此不要在英文中將天文學上的食分與以<a href="/wiki/%E5%B0%8D%E6%95%B8" class="mw-redirect" title="對數">對數</a>尺度表示亮度的<a href="/wiki/%E8%A6%96%E6%98%9F%E7%AD%89"

</p><p>當食分<b>小於1</b>，也就是月球的盤面不能完全遮蔽太陽的盤面。當這兩個盤面的中心幾乎對正時，可以看見環狀的陽光環繞在月球的周圍，這稱為<b>日環食</b>。英文的語源來自<a href="/wiki/%E6%8B%89%E4%B8%81%E6%96%87" class="mw-redirect"

</p><p>同樣的，在一個地點觀測，瞬間的食分也會改變，當食開始時，食分從0.0開始增加，達到一個極大值之後又開始降低，當降至0.0時，這次的食就結束了。而當說食分的值卻又沒有進一步的規範，通常意味著是食甚 (食最大) 時的食分。 </p> <div class="mw-heading mw-heading2"><h2 id="食分與月食的關係"><span
