Our favorite Solar System
Un sistema solar es una estrella y
todo que orbita la estrella
Our sun is not the only star with
planets: 150+ planetary systems
Two examples:
Upsilon Andromeda- very similar to ours
3 planets
PSR B1620-26- solar system with two stars
1 planet
. son
solares
pequeños en términos del
espacio, entonces se mide en
unidades astronómicas
 1 AU = la distancia entre la
tierra y el sol
 1 AU= 150 millones de
kilómetros
 Sistemas
Examples of using AU
¿De dónde viene el sistema solar?
Nuestro sistema solar venía de una nebulosa
Hace entre 4 y 5 millones de años
Gravity caused the Nebula to Collapse
This Caused the Nebula to Begin
Spinning
The Pressure Causes the Center to Ignite
The Sun is born!!!!
What about the planets?
Gravity pulled the left
over gas and dust from
the nebula together
Gravity pulls things towards the
center
Making all the objects ROUND!!!!
Everything in the solar system is
much smaller than the sun

The sun is 99% of all the mass in the solar
system
The first 4 planets
Venus

Planetas terrestres son pequeños
en comparación a planetas
gaseosos.

Anillos
Los planetas terrestres no tienen anillos
 Aunque Saturno es famoso por sus anillos
todos los planetas gaseosos los tienen.

Neptuno
Urano
Objects besides planets
Asteroides
 Asteroides
son rocas giantes
que están orbitando el sol
 They
range in size from about the
size of a classroom to
the largest which is
580 miles long
Asteroids
 La
mayoría de los asteroides
son parte del cinturón de
asteroides entre Marte y
Júpiter.
Cometas
•Cometas están compuestos de
hielo, roca y polvo
•Cometas tienen orbitas muy
elípticas.
Comets
 Comets
have a tail when they
are close to the sun because
of the melting ice
Qué mantiene el sistema solar
en movimiento todos juntos?

The solar system started moving when the
nebula started spinning
Gravedad causa que todo mueve junto.
Main points
Solar systems are a star and what orbits
around it
 Solar systems are measured using A.U.
 In our solar system we have:

the sun
gas planets
terrestrial planets
moons (planetary satellites)
asteroids
comets
