S1 Science
Planet Earth topic
a self-luminous celestial
body consisting of a mass of
gas held together by its own
gravity in which energy is
generated by nuclear
reactions.
the sun and all the celestial
bodies which orbit the sun.
made up of billions of
different “solar systems”.
made up of billions of
different galaxies.
a sphere of rock and/or gas
which orbits a star.
