Summary Space Physics - The Solar System

Complete A-Level / O-Level Physics Notes: Earth, Stars & the Solar System These comprehensive, handwritten study notes cover the full Earth and Space topic for Cambridge O-Level students. Written in clear, structured detail, these notes are perfect for exam revision and are fully aligned with the Cambridge syllabus (Section 6.1 – Earth and the Solar System). What's included across all three documents: 1. The Earth – Covers Earth's elliptical orbit around the Sun, orbital speed and its formula (v = 2πr/T), Earth's axial tilt of 23.5°, the cause of seasons, solstices and equinoxes with dates, day and night lengths, and the Moon's orbital period. Includes clear diagrams of summer/winter solstice and spring/autumnal equinox. 2. The Stars – Covers the life cycle of stars from nebula to protostar, nuclear fusion, the Hertzsprung-Russell diagram, low-mass vs high-mass star evolution, red giants, supernovae, neutron stars and black holes. Also covers galaxies, the Milky Way, light years, the Doppler Effect, red shift, and evidence for the expanding universe and the Big Bang. 3. The Solar System – Covers all eight planets in order, dwarf planets (Pluto, Eris, Makemake), asteroids, meteoroids, comets, the asteroid belt, and the Kuiper Belt. Includes a full data table of planetary properties (mass, density, surface gravity, orbital period, surface temperature) and gravitational field strength formula (g = GM/R²). These notes are ideal for anyone studying Cambridge IGCSE Physics, O-Level Physics, and are a reliable, time-saving revision resource written by a fellow student who understands exactly what examiners are looking for.
