Resumen
Nuestro sistema solar contiene restos de asteroides y cometas de la formación de planetas. Sus estructuras actuales revelan cómo los planetas gigantes se formaron y moldearon el sistema solar exterior, incluido el cinturón de Kuiper y la nube de Oort.
Área de la Ciencia:
- Ciencias planetarias Ciencias planetarias.
- Formación del sistema solar Formación del sistema solar
- La astronomía dinámica es una astronomía dinámica.
Sus antecedentes:
- El sistema solar contiene un disco de cuerpos pequeños (asteroides y cometas) que son restos de su formación.
- La formación planetaria dispersó la mayoría de estos pequeños cuerpos, dando forma a estructuras como el cinturón de Kuiper y la nube de Oort.
- El cinturón de Kuiper y la nube de Oort proporcionan información sobre el sistema solar temprano y la formación de planetas gigantes.
Objetivo del estudio:
- Para analizar la estructura y la dinámica del disco de cuerpo pequeño del sistema solar exterior.
- Comprender los procesos físicos que dieron forma al cinturón de Kuiper y a la nube de Oort.
- Para investigar los orígenes de los cometas de corto período y su conexión con el disco disperso.
Principales métodos:
- Análisis de órbitas cometarias dentro de varias estructuras del sistema solar.
- Modelado de la migración planetaria y las interacciones con cuerpos pequeños.
- Examen de la evidencia de objetos planetarios deshonestos y encuentros estelares.
Principales resultados:

01:16Circular Orbits and Critical Velocity for Satellites
The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.

01:11Energy of a Satellite in a Circular Orbit
Thousands of artificial satellites orbit the Earth every day at various distances from the Earth. Satellites that orbit the Earth below an altitude of 1,600 km are considered to be orbiting in low-Earth orbit (LEO). Research satellites and Earth observation satellites are usually placed in LEO, and mostly orbit the Earth in elliptical orbits. Navigation satellites are placed in medium-Earth orbit (MEO), ranging from 2,000 km to 36,000 km from the surface of the Earth. Meanwhile, communication...
01:10Kepler's First Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. He formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe.
Polish astronomer Nikolaus Copernicus put forth a theory that stated a heliocentric model for the solar system. According to this heliocentric theory, all the planets, including Earth, orbit the Sun in circular orbits.

01:29Kepler's Second Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. His first law states that all planets orbit the Sun in an elliptical orbit, with the Sun at one of the ellipse's foci. Therefore, the distance of a planet from the Sun varies throughout its revolution around the Sun.
While in an elliptical orbit, the total energy of the planet is conserved. Therefore, the planet slows down when it is at apogee and...

01:18Kepler's Third Law of Planetary Motion
In the early 17th century, German astronomer and mathematician Johannes Kepler postulated three laws for the motion of planets in the solar system. In 1909, he formulated his first two laws based on the observations of his forebears, Nikolaus Copernicus and Tycho Brahe. However, in 1918, he published his third law of planetary motion, which gives a precise mathematical relationship between a planet's average distance from the Sun and the amount of time it takes to revolve around the Sun. It...
01:21Schwarzschild Radius and Event Horizon
No object with a finite mass can travel faster than the speed of light in a vacuum. This fact has an interesting consequence in the domain of extremely high gravitational fields.
The minimum speed required to launch a projectile from the surface of an object to which it is gravitationally bound so that it eventually escapes the object’s gravitational field is called the escape velocity. The escape velocity is independent of the mass of the object. Merging the idea of escape velocity with the...
