Rømer va afegir les seves pròpies observacions a les de Cassini i va observar que els temps entre eclipsis (especialment els d'Io) es feien més curts a mesura que la Terra s'acostava a Júpiter, i més llargs a mesura que la Terra s'allunyava. Cassini va fer un anunci a l'Acadèmia de Ciències el 22 d'agost de 1676: </p> <div style="clear:{{#switch:left|center=both|#default=left;"> <table style="margin:auto; width:auto; border-collapse:collapse; border-style:none;"> <tbody><tr> <td width="20" valign="top" style="font-size:35px; padding:0 10px; text-align:left; font-family:'Times New Roman', serif; font-weight:bold; color:silver;">« </td> <td valign="middle" align="left" style="">Sembla que aquesta segona desigualtat es deu a que la llum triga un temps a arribar-nos des del satèl·lit; la llum sembla que triga uns deu a onze minuts [a travessar] una distància igual al mig diàmetre de l'òrbita terrestre<i>.<sup id="cite_ref-24" class="reference"><a href="#cite_note-24"><span class="cite-bracket">[</span>24<span class="cite-bracket">]</span></a></sup></i> </td> <td width="20" valign="bottom" style="font-size:35px; padding:0 10px 10px; text-align:right; font-family:'Times New Roman', serif; font-weight:bold; color:silver;">» </td></tr></tbody></table></div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/Fitxer:Illustration_from_1676_article_on_Ole_R%C3%B8mer%27s_measurement_of_the_speed_of_light.png" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/79/Illustration_from_1676_article_on_Ole_R%C3%B8mer%27s_measurement_of_the_speed_of_light.png/220px-Illustration_from_1676_article_on_Ole_R%C3%B8mer%27s_measurement_of_the_speed_of_light.png" decoding="async" width="220" height="408" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/79/Illustration_from_1676_article_on_Ole_R%C3%B8mer%27s_measurement_of_the_speed_of_light.png/330px-Illustration_from_1676_article_on_Ole_R%C3%B8mer%27s_measurement_of_the_speed_of_light.png 1.5x, //upload.wikimedia.org/wikipedia/commons/7/79/Illustration_from_1676_article_on_Ole_R%C3%B8mer%27s_measurement_of_the_speed_of_light.png 2x" data-file-width="395" data-file-height="733" /></a><figcaption> Il·lustració de l'article de 1676 sobre <a href="/wiki/Velocitat_de_la_llum" title="Velocitat de la llum">la mesura de la velocitat de la llum</a> de Rømer.

En referència a la il·lustració, suposem que la Terra es troba al punt <i>L</i> i Io emergeix de l'ombra de Júpiter al punt <i>D.</i> Després de diverses òrbites d'Io, a 42,5 hores per òrbita, la Terra es troba al punt <i>K</i>.

Va calcular el retard com a proporció de l'angle corresponent a la posició de la Terra determinada respecte a Júpiter, <i>Δt</i> = 22·(<span class="frac nowrap"><sup>α</sup>⁄<sub>180°</sub></span>) [minuts]. Quan l'angle α és de 180° el retard passa a ser de 22 minuts, que es pot interpretar com el temps necessari perquè la llum travessi una distància igual al diàmetre de l'òrbita terrestre, <b>H</b> a <b>E</b>.<sup id="cite_ref-Saito_28-1" class="reference"><a href="#cite_note-Saito-28"><span class="cite-bracket">[</span>28<span class="cite-bracket">]</span></a></sup> (En realitat, Júpiter no és visible des del punt de conjunció <b>E</b>.) Aquesta interpretació permet calcular el resultat estricte de les observacions de Rømer: la proporció de la velocitat de la llum a la velocitat amb què la Terra orbita al voltant del sol, que és la relació entre la durada d'un any dividida per pi en comparació amb els 22 minuts </p><p><span class="frac nowrap"><sup>365·24·60</sup>⁄<sub><i>π</i>·22</sub></span> ≈ 7,600. </p><p>En comparació, el valor modern és aproximadament<span class="frac nowrap"><sup>299,792 km s<sup>−1</sup></sup>⁄<sub>29.8 km s<sup>−1</sup></sub></span> ≈ 10.100.<sup id="cite_ref-29" class="reference"><a href="#cite_note-29"><span class="cite-bracket">[</span>29<span class="cite-bracket">]</span></a></sup> </p><p>Rømer ni va calcular aquesta relació, ni va donar un valor per a la velocitat de la llum.
