Embark on a thrilling journey through our Solar System, exploring the inner planets and space travel possibilities. We start ...

Our Sun, planets, and other objects in the solar system formed from a gigantic cloud of gas and dust more than 4.5 billion years ago.

Before Mercury, Venus, Earth and Mars occupied the inner solar system, there may have been a previous generation of planets that were bigger and more numerous – but were ultimately doomed by ...

A new animation shows the orbits of hundreds of dwarf planets beyond Pluto. The astronomer who compiled the data says it may only capture a small fraction of dwarf planets in the solar system. A ...

Solar System Animation. The planets in our solar system are all different, from composition to rotation speeds and orientation. The concept of how the planets are rotating at different speeds, ...

Earth and Mars were formed from material that largely originated in the inner Solar System; only a few percent of the building blocks of these two planets originated beyond Jupiter's orbit.

Formation of the solar system in two different planetary populations: the inner rocky planets formed earlier than the outer gas and ice giants. (Illustration: Mark A. Garlick / markgarlick.com ...

Scientists suspect that the inner planets of our solar system formed 4.6 billion years ago from a belt of debris that stretched between the current orbits of Venus and Earth.

The “jumping-Jupiter” theory is less harmful to the inner solar system because the orbital coupling between the terrestrial planets and Jupiter is weak if Jupiter jumps.

The Solar System consists of the Sun and the other celestial objects gravitationally bound to it: the eight planets, their 165 known moons, three dwarf planets (Ceres, Pluto, and Eris and their ...

Scientists believe that the solar system was formed by a protosolar nebula (PSN) of gas and some dust. The PSN then condensed to form the Sun, planets, asteroids, and comets. The problem is that the ...

A fifth giant planet was kicked out of the early solar system, according to computer simulations by a US-based planetary scientist. The sacrifice of this gas giant paved the way for the stable ...
