Passage au Périhélie des Comètes |
Un des phénomènes les plus impressionnants de l'Univers nous dévoile peu à peu tous ses secrets.
Crainte de mauvais présages dans l'Antiquité, supposées maintenant avoir joué un rôle majeur dans le développement de la vie sur Terre, les comètes sont une éternelle source d'études et de fascination pour les astronomes amateurs comme pour les professionnels.
Fourmillant de conseils pratiques et d'anecdotes, le livre de Michel Ory nous immerge dans la vie quotidienne de ces chasseurs de comètes. Comment en découvrir une ? Comment se la faire attribuer ? Peut-on déterminer son orbite, calculer sa trajectoire, anticiper son retour ?
On découvre une communauté internationale de passionnés qui, depuis longtemps, contribue sans relâche à l'étude de ces phénomènes célestes. De nombreuses photos et des illustrations réalisées par le dessinateur de presse Pitch Comment viennent enrichir l'ensemble.
Professeur de physique au lycée cantonal de Porrentruy, ancien journaliste et astronome amateur passionné, Michel Ory écume les observatoires aux quatre coins du globe, à la recherche de ces phénomènes célestes. En 2008, par la découverte de 304P/Ory, il intègre la « communauté » des chasseurs/découvreurs de comètes.

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.

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, |
