a planet has it's own weak gravity that pulls the star it's orbiting as it orbits, as the star gets pulled around by the planet, scientist on Earth see the star wobbling, and then they know there is a planet!
We believe that most stars have planets. The first star PROVABLY detected to have a planet was Gamma Cephei.
A planet orbiting a star other than the Sun.An exoplanet is a planet orbiting any other star out there, except the Sun.
Earth orbiting the sun is a planet that is attracted to a star.
Since planets typically orbit their stars in elipses, there is a point in which it is closest, and another point in which it is farthest, from the star. The planet perihelion is when the planet is closest to the star it is orbiting. That is the most basic explanation. =)
the sun
A massive planet (comparable to Jupiter), orbiting around another star, and being very close to the star - so that it has a high temperature.
A planet. It is a large, solid body orbiting its star - the Sun.
The repeating pattern of the stellar motion reveals the presence of a planet orbiting the star. By analyzing the variations in the star's radial velocity, astronomers can determine the planet's mass, orbital period, and distance from the star. This information helps to characterize the planet and understand its orbit within the stellar system.
The star that Earth orbits is the only star that we call the sun. That said, if you lived on a planet orbiting another star, you would probably call that star the sun.
The star they were observing, 51 Pegasi, moved back and forth only very slightly. Therefore, they knew the invisible object could not have enough mass to be a star. They deduced that it must be a planet.
No, the sun is not classified as a planet. It is a star at the center of our solar system, providing light and heat to the planets orbiting around it.
The moon is not a star. The moon is a solid, cold object orbiting a planet, and if it were orbiting alone it is large enough to be considered a planet by itself. A star is a massive ball of gas heated by internal fusion reactions, and weighs millions of times more than the moon.
