Stars, Comets, Magnitude - Coggle Diagram
Stars
ball of plasma held together
by its own gravity
( H :arrow_right: He
Distance calculated in Light-year
Smaller values represent brighter objects
than larger values
Based on T&C ,are, O, B, A, F, G, K, M
Life start in the Nebulae
the contract , become protostar
heat up to a critical mass.( main sequence)
Bigger stars burn fuel faster than smaller so they live longer.
Expan as red giantbut bigger one as red super giant
until ends fuel and then collapse
most turn into nebula
cores burn as White dwarf and remains black dwarf
if is too big the trigger couse an explosion called supernova, if remaining mass is 1.4 bigger thanour sun it collapse in a neutron star

Comets
sun light let gus out, cloud is the COMA,iside it has a solid core the NUCLEUS
Two tails Dust/Gas
Both point away from the sun due to solar wind
Can be more than 100 million km long.
found in Kuiper belt and the Oort cloud
Kuiper is a Doughnut between Neptune and pluto. Oort 1000 times distance than Pluto and sun.
Magnitude
Apparent if measured at an actual distance
Absolute measured at 10 parsec from earth
1 parsec=3.3 light year
