Question

The sun is a mid-sized, main sequence star. What stage is next in the life cycle of the sun?
A red giant
B blackhole
C white dwarf
D neutron star
------------------------
Astronomers study many different kinds of objects in our Solar System. Which of the following best describes a difference between comets and asteroids? *
------------------------
A Comets orbit planets, and most asteroids orbit the Sun.
B Comets are hot balls of gas, and asteroids are made mostly of ice.
C Comets are made mostly of ice, and asteroids are made mostly of rocks.
D Comets orbit the Sun between Mars and Jupiter, and asteroids form patterns in the sky.
------------------------
In November 2013 an object orbiting the sun seemed to disappear behind the sun. When a satellite did not detect the object, astronomers thought that the object had been destroyed when it passed close to the sun. However, when another satellite detected a small, bright object with a fan-shaped tail, astronomers proposed that the object was not destroyed.What type of object were astronomers most likely observing?
A Comet
B An Asteroid
C A meteor
D A nebula
------------------------
Main sequence stars that are much larger and more massive than our Sun will become Super Giants. They will end their life cycle as
A supernova
B nebula
C white dwarf
D neutron star or black hole

Answer 1

For number 1, I do know that the sun is a mid-sized, main sequence star; and the next stage of the sun would be to turn in to a red giant. :-)

Answer 2

The first is white dwarf, not red giant

Answer 3

which one is it

Answer 4

it is red giant first. I'm taking the quiz right now.

Answer 5

IS trahs evrythig because i think
