It has its own url, and it also serves as the kids' portion of the NASA Science Mission Directorate website. [4] The site includes informative articles, hands-on activities, and interactive web games. [2] [3] In addition to its content geared toward children, there are resources for parents and educators. It was one of the first NASA websites ...
Comets whose aphelia are near a major planet's orbit are called its "family". [81] Such families are thought to arise from the planet capturing formerly long-period comets into shorter orbits. [82] At the shorter orbital period extreme, Encke's Comet has an orbit that does not reach the orbit of Jupiter, and is known as an Encke-type comet.
As space objects go, comets and meteors are not very big. The largest asteroid, Ceres, is only about 600 miles wide. Fascinating recent discoveries about comets and meteors in our solar system

Our solar system is full of floating space debris: Comets, meteors, asteroids and more. What are the differences that make up these various space rocks?
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, and comets.
Comet orbits had been determined quite precisely, yet comets were at times recovered "off-schedule," by as much as days. Early comets could be explained by a "resisting medium"—such as "the aether", or the cumulative action of meteoroids against the front of the comet(s). [citation needed] But comets could return both early and late. Whipple ...
