Sirius is not part of our Solar System, so it is not appropriate to talk about "other objects in the solar system".
A solar system.
Neither. The Sun only appears bright because it is close. Sirius is far larger and brighter than our Sun. Our Sun is probably in the top 40% of all stars in the Milky Way, while Sirius is probably in the top 5%. But there are many other stars that are far brighter even that Sirius.
The actor who played Sirius was Gary Oldman. Sirius in the books, was Harry's godfather. Comming from a long line of Slytherins, Sirius was actually put into Gryffindor. He quickly made friends with James Potter, Peter Pettegrew, Remus Lupin and various other people. It was at Hogwarts where Sirius learned how to transform into a black dog to keep Lupin company when he changed into a Werewolf. Sirius was never officially recognised in the wizarding world as an Animagus. When Hogwarts ended for the friends, Sirius Black became Harry Potter's Godfather. After Peter Pettegrew gave the Potters away to Lord Voldemort, Sirius went after him and tried to kill him. His attempts to do so landed Sirius in Azkaban Prison. Sirius escaped in the third book by transforming into the black dog. He went to find Harry, and in that book, the two form a closer bond. It is in later books where we see more to Sirius. We find that he has a home in Grimuald Place and has a pure-blood background. The Black family is very important to the plot of the series. Harry learns many things from his Godfather, and it is perhaps his death in the 5th book that spurrs Harry into action against Voldemort.
Eris is a "dwarf planet", and does not have enough gravity to make the surface round, or to clear other objects near to it.
most stars are made of mainly hydrogen, a little helium and traces of other gases like oxygen
Sirius and the sun share a number of superficial characteristics, since they are both stars. But Sirius is not in the solar system.
Our solar system consists of the sun, the planets, their moons, and a variety of smaller objects. The sun is at the center of the solar system, with other orbiting around it. The force of gravity holds the solar system together.

Sun and other stars, like Sirius are able to produce light of their own.
The planets or other cosmic objects are very different, not similar.
Sirius the Dog Star is the brightest star. However, there are other objects that are brighter. they are Venus (Morning/Evening Star ) and the Moon.
Planets, the sun, asteroids, comets, satellites from the different planets, gases, rocks, etc.

the objects will attract with each other
Standing in the northern hemisphere facing south and then looking up, Sirius will appear below and to the left of the constellation Orion. It is easy to spot as it is the brightest star in the night sky. Sirius A and Sirius B are both part of the same system and are much too close to each other for us to see the distance between them without a powerful telescope. The vast majority of the Sirius' light comes from Sirius A.
The different parts of the Solar System attract one another through gravity. Since the Sun has most of the mass of the Solar System, other objects are mainly attracted to the Sun.
