Solar System
Our solar system is a collection of objects that orbit or are associated with the Sun and its environment. The most notable are the eight official planets, but there are also comets, moons and minor planets, which include dwarf planets. Other concepts applicable to the solar system are the named features on the bodies in it as well as space weather. Explore the solar system using Wolfram|Alpha, which has a diverse set of data and computations for all of these concepts.
Sun
Explore detailed facts about the Sun, which is the most well-studied star, so more is known about it than any other star. Internal structure; models; and dynamic and fixed properties, such as position, mass and luminosity, are included.
Compute the position and path of the Sun:
Get information about the interior of the Sun:
Gather data on moons around most of the planets, and some minor planets, in our solar system.
Compute the location and get properties of a moon:
Compare several moons:
Do computations with properties of planets, moons, etc.:
Get real-time data on space weather phenomena that include concepts such as sunspots, solar wind and the interplanetary magnetic field, which can all interact with each other to produce radio blackouts, possible satellite damage and aurorae on Earth.
Get current space weather conditions:
Query for a specific space weather property:
