Sirius

Sirius was named after the word 'blazing' which fits because it is the brightest star in the night sky AND twice the size and brightness

Sirius is not part of our Solar System, so it is not appropriate to talk about "other objects in the solar system".

Sirius B is a white dwarf, meaning it is already the remnant of a dead star. That star died about 120 million years ago.

most stars are made of mainly hydrogen, a little helium and traces of other gases like oxygen

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.

It's very difficult to age individual stars, but it is estimated that the Sirius system is about 200 - 300 million years old.

Sirius B became a white dwarf about 120 million years ago.

Big stars like Sirius rarely last more than half a quarter billion years.

No. Sirius is a two-star system consisting of a white main sequence star and a white dwarf.

They are Planets - Venus and Jupiter

Sirius is a single star, in the constellation Canis Major, just east of Orion.

It's visible at some time of night during roughly 9 months of the year. The

best time of year to see it depends entirely on what time of night you like to

go outside and look. If you're like most people, and do your gazing between

dinnner and bed-time, then Winter and early Spring are the best seasons.

== == Sirius is the Dog Star, the brightest star (after the sun) in the sky.

It already has. Sirius B is a white dwarf, the dense remnant of a dead star. While it is no longer producing energy through fusion, Sirius B still glows with the leftover heat of when it was an active star. Because of the huge amount of heat and relatively small surface area, it will take trillions of years for Sirius B to cool.

No, because they are not. Sirius A and B are just two stars in a Galaxy of many billions of stars. Sirius is a few hundred million years old, younger than most of the stars in the Milky Way.

You might be referring to a quasar.

Like other stars, Sirius formed when a cloud of gas and dust called a nebula collapsed under the force of gravity. As the cloud collapsed it formed two masses that heated up until the nuclear fusion of hydrogen ignited, turning the two masses into stars by 200 to 300 million years ago. The result was a binary star system consisting of the smaller Sirius A and the larger Sirius B. Since Sirius B was more massive it burned through its hydrogen fuel more quickly and eventually exhausted its fuel supply. By about 120 million years ago it has shed most of its mass while the remainder collapsed into a small, dense remnant called a white dwarf, leaving Sirius A as the larger, more massive body. Sirius A has not yet finished its fuel supply and will likely last for about another 1.5 billion years or so.

No, Sirius is not part of our solar system. The only star in our solar system is the sun.

Sirius is considerably hotter than Antares.

You can't see constellations with a telescope. In fact, you may be looking straight

into one, but you'll never notice it until you come out from behind your telescope.

Sirius is about 8.6 light years away from us.

No. At a distance of only 8.6 light years, Sirius is one of the closest stars to Earth. On a cosmic scale, any star close enough to be visible to the naked eye is fairly close. The farthest stars in the known universe are in other galaxies, billions of light years away.

The features of a Sirius Starmate vary based on the particular model. The Sirius Starmate 7 allows one to view song, artist, and channel information and alerts so one can tune into their favorite songs, artists, and sports. It also features 30 channel presets and parental controls.

Sirius A a white main sequence star is the brightest star in the night sky as seen from Earth and has been known of since there has been astronomy and possibly even before that.

It's dimmer partner Sirius B a white dwarf was first theorised in 1844 by German astronomer Friedrich Bessel based on changes in the proper motion of Sirius A. In 1862 the US astronomer Alvin Graham Clark first observed the white dwarf.

Since 1896 close observations have also suggested that there is a 3rd star or possibly a brown dwarf stellar object in the system of about 0.06 solar masses. However studies done in 2008 now seem to have dispelled this idea.

Sirius is a binary star.

Sirius A has a spectral type of A1V and will appear on the HR in the top left corner.

Sirius B has a spectral type of DA2 and will appear on the HR in the bottom left corner as a white dwarf.
