In planetary geology, the term "ejecta" includes debris ejected during the formation of an impact crater. When an object massive enough hits another object with enough force, it creates a shockwave that spreads out from the impact. The object breaks and excavates into the ground and rock, at the same time spraying material known as impact ejecta.

English: Follow a coronal mass ejection as is passes Venus then Earth, and explore how the sun drives Earth's winds and oceans. Other languages Čeština: Sledování výronu koronální hmoty ze sluneční koróny , který prolétá kolem Venuše a dále naší planety Země a ukazuje, jak tímto způsobem Slunce ovlivňuje pozemskou ...
The three-day May 1921 geomagnetic storm, also known as the New York Railroad Storm, was caused by the impact of an extraordinarily powerful coronal mass ejection on Earth's magnetosphere. It occurred on 13–15 May as part of solar cycle 15, and was the most intense geomagnetic storm of the 20th century. [1]
The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10.It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. [1]
The Fifth Giant is a hypothetical ice giant proposed as part of the Five-Planet Nice Model, an extension of the Nice Model of solar system evolution.This hypothesis suggests that the early Solar System once contained a fifth giant planet in addition to the four currently known giant planets: Jupiter, Saturn, Uranus, and Neptune.

Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
A Martian meteorite is a rock that formed on Mars, was ejected from the planet by an impact event, and traversed interplanetary space before landing on Earth as a meteorite. As of September 2020 [update] , 277 meteorites had been classified as Martian, less than half a percent of the 72,000 meteorites that have been classified. [ 1 ]
