== 观测历史 ==<br />
1861年，[[海因里希·路易·达雷]]在[[哥本哈根大学天文台|哥本哈根天文台]]测试11英寸口径[[折射望远镜]]时发现了NGC 1，他将自己的发现描述为“暗弱的、小的、圆形的、在一颗（位于南方和北方的）11等和一颗14等星之间。”<ref name="cseligman">{{Cite web|url=http://cseligman.com/text/atlas/ngc0.htm#1|title=New General Catalog Objects: NGC 1 - 49|website=cseligman.com|language=en-US|access-date=2017-11-11|archive-date=2018-10-05|archive-url=https://web.archive.org/web/20181005234329/http://cseligman.com/text/atlas/ngc0.htm#1|dead-url=no}}</ref>。1866年和1868年，{{tsl|en|Herman Schultz (astronomer)|赫尔曼·舒尔茨}}曾在[[乌普萨拉]]使用9.6英寸口径的折射式望远镜三次观测到NGC 1<ref>{{Cite web|url=https://astronomy-mall.com/Adventures.In.Deep.Space/NGC%20complete.html|title=NGC 1-7840 complete|first1=Steve|last1=Gottlieb|website=Astronomy Mall|date=2022-01-13|accessdate=2023-02-13|archive-date=2023-02-13|archive-url=https://web.archive.org/web/20230213160610/https://astronomy-mall.com/Adventures.In.Deep.Space/NGC%20complete.html|dead-url=no}}</ref>。<br />
<br />
两位发现者都遗漏了更暗的[[NGC 2]]。NGC 1与NGC 2的[[视距离]]很近，但两个天体相距甚远且没有任何联系。1873年，[[劳伦斯·帕森斯]]发现NGC 2<ref name="cseligman" />。<br />
<br />
== 基本资料 ==<br />
[[File:NGC1 NGC2 - SDSS DR14.jpg|thumb|left|类似[[双星|光学双星]]的NGC 1和NGC 2]]<br />
<br />
NGC 1的约为14万光年，与[[银河系]]（直径约为16万光年）大小相当<ref>{{Cite news|url=https://www.space.com/29270-milky-way-size-larger-than-thought.html|title=Size of the Milky Way Upgraded, Solving Galaxy Puzzle|work=Space.com|access-date=2017-11-12|archive-date=2023-02-12|archive-url=https://web.archive.org/web/20230212094726/https://www.space.com/29270-milky-way-size-larger-than-thought.html|dead-url=no}}</ref>。虽然NGC 1的[[视星等]]仅有13.65等（低于肉眼可见极限），但它的[[绝对星等]]为-22.08，比银河系要[[光度|亮]]两到三倍。<br />
<br />
NGC 1的视尺寸为1.6' × 1.2'<ref name="ned" />。NGC 1拥有一个较弱的[[棒旋星系|核棒]]和松散缠绕的旋臂，依照[[哈伯序列]]和作为拓展的[[佛科留斯系统]]进行[[星系型态分类|分类]]，它属于为SABbc类型<ref name="Class">{{cite journal|last=de Vaucouleurs|first=Gérard|title=Revised Classification of 1500 Bright Galaxies|journal=Astrophysical Journal Supplement|date=April 1963|volume=8|page=31|doi=10.1086/190084|bibcode = 1963ApJS....8...31D }}</ref>。虽然它的星系核心直径仅为9万光年，但可能来自于先前星系并合遗留的、巨大且弥散的旋臂使它变得更大。<br />
<br />
NGC 1的[[红移]]约为0.015，基于此可以得出它的[[退行速度]]约为{{Val|4450|u=km/s}}<ref name="ned" />，由[[哈勃定律]]可计算出它与太阳系的距离约为2.10-2.15亿光年，与不使用红移的测距方法得到的结果（1.75到2.45亿光年）相吻合。此外，该星系的退行速度曾被测为{{Val|2215|u=km/s}}，即它距离地球仅有1亿光年。然而，这个测量结果不被大多数天文学家所接受，应当是另一星系的测量值被错用在NGC 1上了<ref name="cseligman" />。<br />

== 天体目录的收录 ==<br />
NGC 1是[[星雲和星團總表]]和其继任者[[星云和星团新总表]]（即NGC天体表）的第一个天体。<ref name="ned"/>在新总表编纂完成时NGC 1的[[赤经]]为{{RA|00|00|4}}（J1860[[历元]]），这使得它以星表所有天体中赤经最低的身份，在按照赤经从低到高排序的表中排在首位。<ref>Dreyer, J. L. E., "New General Catalogue of Nebulae and Clusters of stars (1888)", ''Memoirs of the Royal Astronomical Society'', '''49'''. p3, Royal Astronomical Society, 1962.</ref>在此之后，由于[[岁差]]，它的坐标发生了变化，不再是NGC星表中天体中赤经最低的那一个。<ref>Erdmann, R.E., Jr., ''The Historically Corrected New General Catalogue of Nebulæ and Clusters of Stars'', p12, [http://www.ngcic.org/public_HCNGC/The_HCNGC_intro.pdf 检索] and [https://web.archive.org/web/20200620062609/https://www.ngcic.org/public_HCNGC/The_HCNGC_intro.pdf 存档] 13 June 2008.</ref><br />
