This Topical Collection (TC) is devoted to the recent advancement in the study of Earth-affecting solar transients. Earth-affecting solar transients encompass a broad range of phenomena, including major solar flares, coronal mass ejections (CMEs), interplanetary CMEs (ICMEs), solar energetic particle (SEP) events, and corotating interaction regions (CIRs). In the past decade, nearly continuous observations of the Sun and the inner heliosphere with an unprecedented wide spatial coverage from a fleet of spacecraft, including the Solar Terrestrial Relations ObservatoryAhead/Behind (STEREO A/B), the Solar Dynamics Observatory (SDO), the Solar and Heliospheric Observatory (SOHO), the Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) spacecraft, Venus Express (VEX), the Advance Composition Explorer (ACE), and Wind, in combination with a significant development and improvement of global magnetohydrodynamics (MHD) numerical simulations and theoretical analyses, have greatly improved our understanding of solar transients and the prediction of their potential impact on Earth. This TC includes articles that address, but are not limited to, the following questions: (1) How do various geoeffective phenomena originate on the Sun? (2) How do they propagate and evolve in the inner heliosphere? (3) How can we reconcile in situ and remote-sensing data on transients? (4) How can we predict the probability of arrival, time of arrival, and geoeffectiveness of these phenomena? (5) Which type of solar wind transients are geoeffective, and why?
