Alguns dels procediments emprats en el passat avui en dia s\u00f3n obsolets per manca de precisi\u00f3, d’altres s’han millorat amb nous instruments i s\u00f3n imprescindibles per arribar a mesurar dist\u00e0ncies cada cop m\u00e9s grans. I \u00e9s que els diferents m\u00e8todes que s’apliquen a les diferents dist\u00e0ncies no s\u00f3n independents entre ells. Per estimar la dist\u00e0ncia a la gal\u00e0xia m\u00e9s llunyana cal saber la que ens separa de gal\u00e0xies properes. Alhora aquestes dist\u00e0ncies properes no es podrien calcular sense saber abans a quina dist\u00e0ncia s\u00f3n les estrelles i quina dist\u00e0ncia ens separa del Sol.La mida de l’Univers es calcula comen\u00e7ant pel cossos que tenim m\u00e9s a prop i anant cada vegada m\u00e9s lluny, amb procediments successius i depenents.
