Solar system
  1. The Solar System consists of the Sun, eight planets, moons, dwarf planets, asteroids, comets, and other celestial objects.
  2. The Sun is the center of the Solar System and accounts for 99.86% of its total mass.
  3. The eight planets are classified as terrestrial planets (Mercury, Venus, Earth, Mars) and gas giants (Jupiter, Saturn) and ice giants (Uranus, Neptune).
  4. Mercury is the closest planet to the Sun and has no atmosphere to retain heat.
  5. Venus has a thick atmosphere rich in carbon dioxide, causing a strong greenhouse effect.
  6. Earth is the only planet known to support life due to its favorable atmosphere and liquid water.
  7. Mars, the "Red Planet," has the largest volcano in the Solar System, Olympus Mons.
  8. Jupiter is the largest planet and has the Great Red Spot, a giant storm system.
  9. Saturn is famous for its extensive ring system made of ice and rock particles.
  10. Uranus rotates on its side, with an axial tilt of about 98 degrees.
  11. Neptune is the farthest planet from the Sun and has the strongest winds in the Solar System.
  12. Dwarf planets include Pluto, Eris, Haumea, Makemake, and Ceres.
  13. Asteroids are rocky objects, mostly found in the asteroid belt between Mars and Jupiter.
  14. Comets are icy bodies that release gas and dust when they approach the Sun, forming a glowing tail.
  15. The Kuiper Belt is a region beyond Neptune filled with icy bodies and dwarf planets.
  16. The Oort Cloud is a hypothetical region of icy objects surrounding the Solar System.
  17. Gravitational forces from the Sun and planets govern the motions of celestial bodies in the Solar System.
  18. Planets revolve around the Sun in elliptical orbits as described by Kepler's Laws of Planetary Motion.
  19. The Earth's Moon is the fifth-largest natural satellite in the Solar System.
  20. The heliosphere is the bubble-like region of space influenced by the solar wind and magnetic field of the Sun.
  21. The Sun generates energy through nuclear fusion, converting hydrogen into helium.
  22. Planets are categorized based on their proximity to the Sun: inner planets (Mercury to Mars) and outer planets (Jupiter to Neptune).
  23. The ecliptic plane is the flat plane on which most planets orbit the Sun.
  24. Planetary rings are a characteristic feature of gas giants like Saturn, Jupiter, Uranus, and Neptune.
  25. Exoplanets are planets outside our Solar System that orbit other stars.
  26. The solar wind is a stream of charged particles released by the Sun.
  27. Day and night on Earth are caused by its rotation, while the changing seasons are due to its axial tilt and revolution around the Sun.
  28. Gravity keeps the Solar System bound together and governs the orbits of all celestial bodies.
  29. The Trojan asteroids share Jupiter's orbit, leading or trailing the planet at stable points.
  30. Trans-Neptunian Objects (TNOs) are celestial objects located beyond Neptune's orbit.
  31. Solar eclipses occur when the Moon passes between Earth and the Sun, casting a shadow on Earth.
  32. Lunar eclipses occur when Earth passes between the Sun and the Moon, casting its shadow on the Moon.
  33. The Goldilocks Zone, or habitable zone, is the region around a star where conditions may be suitable for liquid water.
  34. Retrograde motion is the apparent backward motion of planets as observed from Earth, caused by differences in orbital speeds.
  35. The Milky Way Galaxy is the galaxy that contains our Solar System.
  36. Space probes like Voyager and New Horizons have provided detailed data about the outer Solar System.
  37. The solar constant is the amount of solar radiation received per unit area at Earth's distance from the Sun.
  38. Auroras occur when solar wind particles interact with Earth's magnetic field and atmosphere.
  39. The Sunspot Cycle is an 11-year cycle of varying solar activity and sunspot numbers.
  40. Light years measure the distance light travels in one year, used for measuring interstellar distances.
  41. The International Astronomical Union (IAU) defines the classifications and naming conventions of celestial bodies.
  42. Gravitational assists are techniques used by spacecraft to gain speed by passing near planets.
  43. The Geocentric Model proposed Earth as the center of the universe, later replaced by the Heliocentric Model.
