How hot is the core of Sirius?
Sirius is hotter than the sun. -------------------------------------- The temperature at the surface of Sirius is estimated to be 9 440 K. The temperature at the surface of Sun is estimated to be 5 778 K.
What objects in space produce light?
Sun and other stars, like Sirius are able to produce light of their own.
What is the size of Sirius?
Sirius has a mass 0.978 that of the Sun, and a radius 0.0084 times that of the Sun. No, actually Sirius A has a mass of 2.2 that of the Sun and a radius 1.711 times that of the Sun.
What is the difference between Sirius and Proxima Centauri?
Proxima Centauri is a red dwarf star and the nearest star to us other than the sun. It is about 4.2 light years away and is much dimmer than the sun, too dim to be seen with the naked eye. It is unclear whether it is part of the Alpha Centauri system. Sirius is a binary star system consisting of a white dwarf stellar remnant and a white main sequence star about 25 times brighter than the sun. Sirius is one of our closest stellar neighbors at about 8.6 light years away. It is the brightest star in the night sky.
A star's absolute magnitude is its apparent brightness as seen from?
The Sun with an apparent magnitude of -26.74. Followed by Sirius with an apparent magnitude of -1.46
How long does Sirius take to orbit the sun?
Sirius does not orbit the Sun.
Is sirius a cold?
No. Sirius is far from a cold star. Sirius is actually a binary system about 8.6 light years away. Sirius A is a white main sequence star just over twice the size of the sun. Sirius B is a white dwarf stellar remnant of about 0.978 solar masses. The temperature of the two stars are far higher than that of our sun. The sun is about 5778 Kelvin, Sirius A is almost twice that at 9,940 K and Sirius B is many times that at 25,200 K.

How old is the star sirius?
From Wikipedia: "The age of the system [Sirius is a double star] is estimated at around 230 million years." So, a fairly young star, at least if compared to typical stars, including our own Sun.
Is Sirius closer to the Sun or Pluto?
that depends on where pluto is in its orbit (think of sirius as the hub of your front bike wheel, the sun as the hub of the back wheel and pluto as the valve for the back wheel inner tube) with the vast distance from the sun to sirius (8.6 light years) the percentage of how much closer it is to pluto or the sun will be tiny, but its still a measurable difference. (pluto is only about 4 light HOURS from the sun)
How does Sirius receive it's light?
Sirius does not receive or reflect light, it transmits or radiates light. Sirius is a Star and thus similar to our Sun and thus converts Hydrogen into light by nuclear fusion.
Is Sirius closer to earth than Rigel?
Sirius is a star, not a planet, and it is not the closest star to Earth or anywhere near being the closest (technically the closest star to Earth is the sun, and the next closest is Proxima Centauri).
What is the brightest star a sun star or night star?
Our sun is brighter because it is only 0.000 000 016 light years away(149,320,000km.) The brightest star in the night is Sirius. It is 8.8 light years away. So a sun star is a brighter star
How much light doe the sun provide than sirius?
Sirius is about 25 times as bright as our Sun. That refers to the absolute magnitude; of course, our Sun looks much brighter to us, because it is closer.
Jupiter ishow many light years from the sun?
0.000082235 light years
