Asteroids are the leftovers from the formation of the solar system. The planets came together about 4.6 billion years ago, with the rocky planets forming closest to the Sun. The asteroid belt, between Mars and
In our own solar system, there are numerous celestial objects that have solid, rocky surfaces that are worth exploring. This includes the planets, moons, dwarf planets, asteroids, and comets. Much of these bodies' geology is similar to what we find on Earth, but much of it is also complet...

A smaller number of satellites turn their "eyes" toward space, where they capture magnificent vistas of stars, planets and galaxies and scan for objects, such as asteroids or comets, that could be heading for a collision course with Earth....

Because these exoplanets exceed the compositional spread of >4,000 nearby main sequence stars, their unique silicate compositions are unlikely to reflect variations in parent star compositions. Instead, polluted white dwarfs reveal greater planetary variety in our solar neighborhood than currently ...
Example. There are many planets and satellites, asteroids and other objects in the solar system, but there is only one star, which is the sun. It exists from the beginning of the solar system. If another sun is added (another object) to the solar system or if the sun changes its behav...
The principal driving force behind meteorite studies is the fact thatsmall bodiessuch as asteroids and comets are most likely to preserve evidence of events that took place in the early solar system. There are at least two reasons to expect that this is the case. First, when the solar system...
Spaceflight, flight beyond Earth’s atmosphere. This article deals with the basic concepts associated with the launch and return of unmanned and manned spacecraft and their travel, navigation, and rendezvous and docking in space. For the development of s
