Lista de asteroides

Origem: Wikipédia, a enciclopédia livre.

Esta é umalista deasteroides ordenados sequencialmente.

Atésetembro de2004 mais de 90 000 já tinham sido numerados (e outros tantos estavam em lista de espera).

Muitos dos asteroides partilham características comuns, não sendo, portanto, de notabilidade.

Convenção de nomenclatura e numeração

[editar |editar código]

Após serem descobertos, os asteroides geralmente recebem nomes sistemáticos (como1989 AC) e, entretanto, um número (como 4179). Podem, opcionalmente, receber um nome também (comoToutatis).

Atualmente os asteroides recebem números sequenciais apenas quando a suaórbita está documentada com precisão. Os que não preenchem este requisito (ainda) mantêm a sua designação sistemática. Esta regra não foi usada desde sempre, existindo assim vários asteroides que receberam um número e cujo rasto foi, entretanto, perdido. Porém, já se conseguiu a sua recuperação; o último asteroide a ser recuperado foi719 Albert e, embora não se consiga observar1915 Quetzálcoat e(3360) 1981 VA desde1985,[1] as suas órbitas são conhecidas e aproximações daTerra estão previstas para2062 e2085, respectivamente.

Pelas razões supra-citadas, a sequência dos números apenas se aproxima da cronologia da descoberta. Em casos extremos, como asteroides "perdidos", podem-se verificar discrepâncias: por exemplo,69230 Hermes foi originalmente descoberto em1937, mas foi "perdido" até2003. Só depois da sua recuperação se conseguiu documentar a sua órbita e atribuir-lhe um número. Antes disso, era conhecido apenas por 1937 UB (o seu nome sistemático).

Só posteriormente à atribuição do número é que o asteroide se torna um candidato ao "baptismo" (atribuição de nome) — por largos anos, Hermes foi uma rara excepção, já que nunca foi numerado. Geralmente são concedidos 10 anos ao responsável pela descoberta para escolher um nome; alguns asteroides ficam, porém, sem nome atribuído. Especialmente no final doséculo XX, com os programas automatizados de rastreio de asteroides, como oLINEAR, a velocidade das descobertas aumentou em tão larga escala que a maioria destas descobertas dificilmente irá receber um nome.

Em casos excepcionais, um objecto atípico (não convencional) pode receber um nome não-oficial previamente ao número. Um exemplo recente é90377 Sedna, que apenas dispunha do nome sistemático2003 VB12 antes de ser numerado (90377) e, pouco depois, baptizado em Setembro de2004.
