Orbits, Kepler and Newton laws ..English andFrenchPRESENTATION:This software can calculate orbits of the planets of the solarsystem. A planet , size of an asteroid can also be created.A satellite can be placed in orbit , trajectory is an ellipse or ahyperbola in the conditions of position and initial velocity. Aftercalculation, a simulation of the movement is feasible.The main data of the trajectory can be displayed properlyDESCRIPTIONA first line of buttons allows you to choose a planet around whichwill evolve the satellite; with the Plx button you can define anasteroid or a planet giving the mass; the minimum mass is 100million tonnes, an asteroid of nearly 1km in diameter; the otherbuttons include the planets of the solar system with theirdimensions and masses known.The second line is used to define the distance unit and distance(A.U. or astronomical unit (average distance from the Earth to theSun), E6 km (1 million km), E3 Km (1000 km) and Km; for example,choosing the planet Ea(earth) and E3 and 10 on the keyboard gives adistance of 10 000 km, the satellite is up to 10 000 km from thecenter of the earth on the X axis (horizontal).An indication of the satellite velocity is given for a circularpath and the top speed for an elliptical trajectory.On the third line is defined radial velocity (Vx) and thetangential speed (Vy) in km / sec.Finally the Calculation button launches the trajectorycalculation; the data button gives the main data of thetrajectory.(Hide with long click)If the distance is not changed, several calculations can be runshowing the trajectory of changes following the speedchanges.A simulation button starts a movement of the satellite on itstrajectory; Long press Stop returns to the calculations page.The language may be amended after a long press on Information andreboot.In example (data from earth to perihelion)-Planete S-Distance, Choice Km and 147,098,074-Speed X: 0, y speed: 30.291or (international station)-Planete Ea-Distance, Choice Km and 6720-Speed Vx: 0, Vy: 7.7or (Rosetta)-Planete Plx and 100 for a mass of the comet P67 of 1E13 Kg-Distance 15 Km-speed X 0, y = 0.00025----------------------------For information, perihelion and speed (at per)of planets of solarsystem:Mercure 46,001,272 Km 58.98 Km / sVenus 107,476,259 35.26Earth 147 098 074 30.291Mars 206 644 545 26.5Jupiter 740,520,000 13.71Saturn 1349 467 375 10.183Uranus 2748 938 461 7.1Neptune 4452 940 833 5.487Orbites , lois de Kepler et NewtonPRESENTATION:Ce logiciel permet de calculer des orbites autour des planetes dusysteme solaire.Ici , le satellite en orbite a une massenégligeable devant la planete (comme la terre autour du soleil) etn'a pas d'infuence sur le mouvement de la planète (pas comme lalune , qui dans sa rotation , fait bouger la terre) Une planete dela dimension d'un asteroide peut aussi etre cree .Un satellite peut etre place en orbites et la trajectoire sera uneellipse ou une hyperbole selon les conditions de position et devitesse initiale.
