    en.wikipedia.org/wiki/Fifth_Giant_(hypothetical...

    The ejection of the Fifth Giant is believed to have occurred during the early Solar System's period of instability, when gravitational interactions between the giant planets became chaotic. [3] The planet likely encountered a series of close gravitational encounters with Jupiter or Saturn, resulting in its eventual expulsion from the Solar System.

    en.wikipedia.org/wiki/Ejecta

    Beside material launched by humans into space with a range of launch systems, some instances particularly nuclear produce artificial ejecta, like in the case of the Pascal-B test which might have ejected an object with a speed of Earth's escape velocity into space. [13] [14]

  4. Coronal mass ejection - Wikipedia

    en.wikipedia.org/wiki/Coronal_mass_ejection

    A coronal mass ejection (CME) is a significant ejection of plasma mass from the Sun's corona into the heliosphere. CMEs are often associated with solar flares and other forms of solar activity , but a broadly accepted theoretical understanding of these relationships has not been established.

    en.wikipedia.org/wiki/Carrington_Event

    The geomagnetic storm is thought to have been caused by a big coronal mass ejection (CME) that traveled directly toward Earth, taking 17.6 hours to make the 150 × 10 ^ 6 km (93 × 10 ^ 6 mi) journey.

    Artist's depiction of a collision between two planetary bodies. Such an impact between Earth and a Mars-sized object likely formed the Moon.. The giant-impact hypothesis, sometimes called the Theia Impact, is an astrogeology hypothesis for the formation of the Moon first proposed in 1946 by Canadian geologist Reginald Daly.
