What is the difference between a planetary object and a moon?
A planetary body is a non-luminous object rounded by it's own gravity that orbits a star or a stellar remnant. A moon, or satellite, orbits a planetary body.
What is the magnitude of Cassiopeia A?
Cassiopeia A is a supernova remnant in the constellation Cassiopeia.It has no single point of luminosity, so no definitive magnitude can be attributed to it.
Make a sentence for astronomy?
An asteroid is a bunch of rocks moving through out solar system
How far is the closest star to earth?
The closest supernova, or more correctly supernova remnant, is the Vela supernova remnant [See Link] in the constellation Vela. The "guest" star exploded about 11 - 12,000 years ago and is located around 800 light years from Earth.
What is the difference between the protostar and the white dwarf?
A protostar is a star that is in the early stages of formation that has not yet become a main sequence star. A white dwarf is a remnant left behind after a low to medium mass star dies.
What are the 5 kinds of nebulea?
The 5 types of cosmic nebulae are: Reflection Emissive Dark Planetary Supernova remnant
What is the difference between a planetary object and a moon?
A planetary body is a non-luminous object rounded by it's own gravity that orbits a star or a stellar remnant. A moon, or satellite, orbits a planetary body.
Can a pulsar change into a supernova?
No. A pulsar is a remnant left behind by a supernova.
What Remnant can stretch over a distance of several light-years?
A supernova remnant.
What are examples of nebulae?
Planetary nebulae (the cat's eye nebula) Emission nebulae (the orion nebula) Dark nebulae (the horsehead nebula) Supernova remnant nebulae (the crab)
Why is the Crab Nebula considered a supernova remnant?
Because it IS a supernova remnant. It's the visial remains of a star that expolded and was seen in 1054. Designated SN 1054.
How big is supernova cassiopeia?
Currently the expanding cloud from the supernova remnant is about 10 light years across.
What might happened to a star after it explodes as a supernova?
The supernova remnant will either be a neutron star or a black hole.
The Crab Nebula is a supernova remnant In which constellation is it located?
In the constellation of Taurus
A spinning neutron star has been observed at the center of a?
supernova remnant
What determines what stage comes after a supernova?
The amount of mass in the remnant. If the mass of the remnant exceeds 3 solar masses then it will become a black hole.
What remnant does a supernova leave?
Depending on the mass of the original star, it is either a black hole or a neutron star.
