Red Dwarfs, M type stars (based on stellar classification)
The first planet from the sun:
Mercury, also the smallest
The Earth is big?
No, it is small compared to even a planet in the solar system
The galaxy we live in is:
The Milky Way Galaxy!
The smallest black hole possible based on theory is
A primordial black hole, a black hole with the mass of an average mountain, but the size of a proton!
The sun's diameter is:
1,392,700 km Other answers:1.3 Million km,1.39 million, 1.392 million, 1.3927 million
The largest planet is:
Jupiter!
The percent of the mass of the solar system is made up by the sun=
99.86% of all of the solar system's mass.
There are ___ at the core of galaxies
Supermassive or ULTRAMASSIVE black holes
How black holes form?
Compress anything to a certain size, it will transform (ex: the Earth would have to be compressed to the size of a coin to transform).
The closest star to Earth is ___ at ___ light-years.
Proxima Centauri, 4.54 light-years.
The dwarf planets are:
Ceres, Pluto, Haumea, Makemake,and Eris.
The most massive object to exist is:
The Observable Universe itself!
What are the most massive stars to ever exist?
Quasi-Stars/Black hole stars.
Name all the types of black holes:
Primordial, Stellar, Supermassive, ULTRAMASSIVE!
The largest Main-Sequence star is:
R136a1: A blue star about 300x the mass of the sun.
What is beyond the Kuiper Belt?
A place of mostly empty space, called the Scattered Disk.
Will black holes ever die?
Yes! They will, but it will take about 1010 to the power 29 years.
What happens when a Quasi-Star forms?
The core of the star collapses into a black hole and a powerful shockwave rips through the universe.
The largest black hole is:
TON 618 or a newly discovered black hole called Phoenix A*
What is the largest star in the universe?
Stepheson 2-18 is a red hypergiant, the largest star in the universe, at 2150x the sun's size.
Where is the end of the solar system?
That would be about 3500 AU away from the sun, at the possibly existing Oort Cloud.
Is life rare in the universe?
We don't know. We do not have the technology yet to find this answer.
What created the Universe?
The best possible theory states that the Universe started as a singularity and then exploded and our universe was created.
What is the highest known mass of any black hole?
66 billion x the Sun is the highest known mass set by TON 618. But, another black hole might dethrone TON 618 as the biggest object in the universe.
