A solar storm is a disturbance on the Sun, which can emanate outward across the heliosphere, affecting the entire Solar System, including Earth and its magnetosphere, and is the cause of space weather in the short-term with long-term patterns comprising space climate. [1] [2]
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.
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.
The solar storm of 2012 was a solar storm involving an unusually large and strong coronal mass ejection that occurred on July 23, 2012. It missed Earth by a margin of roughly nine days, as the Sun's equator rotates around its own axis once over a period of about 25 days. [1]
Earth tends to pull asteroids into partial or full orbits around it regularly before they are flung back out into space. For instance, one such space rock 2022 NX 1 was a short-lived “mini-moon ...
STEREO (Solar TErrestrial RElations Observatory) is a solar observation mission. [2] Two nearly identical spacecraft (STEREO-A, STEREO-B) were launched in 2006 into orbits around the Sun that cause them to respectively pull farther ahead of and fall gradually behind the Earth.
This causes their hold on their upper layers to weaken allowing small disturbances to blast large amounts of the outer layers into space. Events such as solar flares and coronal mass ejections are mere blips on the mass loss scale for low mass stars (like our sun). However, these same events cause catastrophic ejection of stellar material into ...
