Have astronomers found a sun like ours, not just a star, but one ...?

Question

that has the shape and magnitude of our own sun?

Answer 1

Here are a few stars like our sun *AND* have planets orbiting about them --
HD 187123
OGLE-TR-56
TrES-2
55 Cnc

Answer 2

All stars have the same basic shape, that of a spheroid. That shape will be modified to a greater or lesser degree depending on the rotation rate of the star in question, becoming flatter the faster it rotates. As far as magnitude and stellar type, the answer is yes. They have identified many, many stars which are similar to ours.

Answer 3

well all stars are spherical, give or take. stars can be characterised by magnitude, spectral class, mass, metallicity, rate of rotation, age, and so forth. it depends how exactly you specify the parameters... there would be anywhere from billions to a few million stars like the sun in the milky way galaxy. most star catalogs only have information about position, magnitude and spectral class though, and even there, the catalogs contain only a few million stars. statistically we would expect to find a certain number of sun-like stars though.

Answer 4

There are hundreds, maybe thousands of G type stars like our Sun just in the relatively near regions of the Universe. Common as muck, mainly because they last a fair while.

Answer 5

Yes. There are 300 billion stars in the Milky Way galaxy alone. They're a dime a dozen.

Answer 6

Chara (Beta Canum Venaticorum)

Answer 7

Yes.
