Distance moyenne de la Terre au Soleil = 1 UA = 149.597.870 km

 

La Période de révolution est donnée par la formule :

Période=

avec a= demi-grand axe de l'orbite en UA

en application de la 3ème loi de Kepler : Les carrés des temps des révolutions sidérales sont proportionnels aux cubes des grands axes de leurs orbites.

Les Comètes observables en Mars 2006 

 

Observez la comète 9P/Tempel, cible de la mission Deep Impact

 

C/2004 Q2 (Machholz)

La dixième comète découverte par Donald Edward Machholz, visible à la magnitude 5.0 en Janvier 2005

 

C/2004 H6 (SWAN)

Une quatrième comète découverte sur les images de l'instrument SWAN du satellite SOHO, visible en Juillet pour les observateurs de l'hémisphère nord

 

Trois comètes très brillantes dans le ciel

 

La comète C/2004 F4 (Bradfield)

une comète brillante, la 18ème découverte de William Bradfield

 

La comète 2P/Encke

Le 59ème retour au périhélie de la comète 2P/Encke depuis sa découverte en 1786.

 

C/2003 K4 (LINEAR)

Une comète de mag 5.2 au plus fort de son activité...mais mal placée pour l'observation dans l'hémisphère Nord.

 

C/2002 Y1 (Juels-Holvorcem)

 

La comète X5 visible dans le champ de SOHO du 25 au 30 Janvier 2003 (attention : cette page comprend deux animations de 1467ko et 550ko et peut donc s'avérer être longue à charger)

 

C/2002 X5 (Kudo-Fujikawa)

 

C/2002 V1 (NEAT)

 

La comète V1 visible dans le champ de SOHO du 16 au 20 Février 2003 (attention : cette page comprend une animation de 718ko et peut donc s'avérer être longue à charger)

 

C/2002 T7 (LINEAR)

 

SOHO : la 500è comète découverte depuis 1995

 

C/2002 O7 (LINEAR)

 

C/2002 O6 (SWAN)

 

C/2002 O4 (Hoenig)

 

C/2002 F1 (Utsunomiya)

 

C/2002 E2 (Snyder-Murakami)

 

C/2002 C1 (Ikeya-Zhang)

 

C/2001 Q4 (NEAT)

 

C/2001 A2 (LINEAR)

 

C/2000 WM1 (LINEAR)

 

Au fur et à mesure qu'une comète s'approche du Soleil, une partie de la glace composant son noyau se vaporise, entraînant l'apparition d'une enveloppe gazeuse, la chevelure ou "coma". Les gaz et poussières expulsés, repoussés par le vent solaire et la pression du rayonnement solaire, composent alors les queues (de poussières et de plasma) de la comète, en direction opposée au Soleil.

 

 

 

A proximité du périhélie, la comète est à son maximum de dégazage et en conséquence, les queues de poussières et de plasma atteignent leur plus grande longueur.

 

Quelques comètes, subissant au maximum les effets gravitationnels du Soleil, ne résistent pas et se brisent en plusieurs morceaux au cours de leur approche au plus près du Soleil, devenant ainsi beaucoup plus lumineuses.

 

C'est à l'approche du Soleil que se forme une queue de poussières,

toujours dirigée à l'opposé du Soleil.
