Content on Space Place is broken into six subject matter categories: Universe, Sun, Earth, Solar System, Science and Technology, and Educators. [5] [6] Users can also sort material by articles, activities, and games. [6] Over 40 missions are represented on the Space Place. [7]
The Solar System [d] is the gravitationally bound system of the Sun and the objects that orbit it. [11] ... As of 2024, NASA lists 26,182 confirmed Mars-crossing ...
NASA also launched probes to the outer Solar System starting in the 1960s. Pioneer 10 was the first probe to the outer planets, flying by Jupiter, while Pioneer 11 provided the first close up view of the planet. Both probes became the first objects to leave the Solar System.
This phenomenon has been observed outside the Solar System, around stars other than the Sun, by NASA's now retired orbital GALEX telescope. The red giant star Mira in the constellation Cetus has been shown to have both a debris tail of ejecta from the star and a distinct shock in the direction of its movement through space (at over 130 ...
This is the boundary of the Solar System to interstellar space. The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away.
An artist's concept of a planetary system. A planetary system is a set of gravitationally bound non-stellar bodies in or out of orbit around a star or star system.Generally speaking, systems with one or more planets constitute a planetary system, although such systems may also consist of bodies such as dwarf planets, asteroids, natural satellites, meteoroids, comets, planetesimals [1] [2] and ...
The Solar System travels alone through the Milky Way in a circular orbit approximately 30,000 light years from the Galactic Center. Its speed is about 220 km/s. The period required for the Solar System to complete one revolution around the Galactic Center, the galactic year, is in the range of 220–250 million years. Since its formation, the ...
In one of the episodes the show has a live interview with NASA astronauts in space aboard the International Space Station. [4] [5] Marshall and DuFort had previously collaborated on improvisational comedy at The Second City. [6] The show interviewed Chris Hadfield, the first Canadian to walk in space. [7] [8] The podcast is produced in Chicago. [9]
