href="/wiki/Gliese_876" class="mw-redirect" title="Gliese 876">Gliese 876</a>一颗达地球质量6至8倍的行星，可能拥有岩石结构。 </p><p>人们对新发现的大型系外行星仍未完全了解，大多估计其物质构成与太阳系的大型行星类似，又或是从未见过的大型<a

title="碳行星">碳行星</a>。值得注意的是，一些大型行星在极接近恒星的地方公转，拥有近乎完美的圆形轨道，这些行星被称为「<a href="/wiki/%E7%83%AD%E6%9C%A8%E6%98%9F" class="mw-redirect" title="热木星">热木星</a>」，它们比太阳系的大型行星接受更大量的<a

planet）是環繞其他恆星公轉的行星，長久以來，人們認為其他恆星和太陽一樣，均有行星環繞其恆星公轉，但一直未能證實。直至1992年<a href="/wiki/PSR_B1257%2B12" title="PSR B1257+12">PSR B1257+12</a>被證實以來，至今已有百多個太陽系外行星被發現。這些發現增加了對<a

title="脈衝星">脈衝星</a>PSR B1257+12的三顆與類地行星相若的天體，以及位於天壇座μ星的一顆有14個地球質量的行星。 </p><p>也有一種行星，沒有圍繞特定的恆星公轉，它們像是宇宙的流浪客，稱為<a href="/wiki/%E6%98%9F%E9%9A%9B%E8%A1%8C%E6%98%9F" title="星際行星">星際行星</a>（Interstellar

<p>天體測量法是搜尋太陽系外行星最古老的方法。這個方法是精確地測量恆星在天空的位置及觀察那个位置如何随着時間的改變而改變。如果恆星有一顆行星，则行星的<a href="/wiki/%E4%B8%87%E6%9C%89%E5%BC%95%E5%8A%9B" class="mw-redirect"
