The center of the orbit is between them in proportion to their masses. But the mass of the sun is so much larger compared to the mass of the planets that to a casual observer they do revolve around the center of the sun.
Because planets don't orbit the exact center of stars, astronomers can see stars that "wobble" and can tell they have planets orbiting them. They will also get an idea of the period of those planets' revolutions around the star.

Constellations appear to move, because the earth is spinning on it's own axis.
Only the earth and the planets revolve around the sun.
The planets that you can see in the sky, do not form any part of a constellation. They move relative to the constellations and wander about.
'Planet' is Greek for Wanderer.

∙ 14y agoYes all planets revolve around the sun except the moons of the planets which revolve around their own planets.

∙ 8y agoNo. The sun is just one star of billions in our galaxy. The sun along with all the other stars orbits the center of the galaxy.

∙ 13y agono, the sun orbits around the galactic center

∙ 8y agoNo. The sun is a star, one of billions in the galaxy. All of these stars orbit the galaxy's center.

How many planets rotate clockwisegive the names?
Within the nine old planets, 3 of them have retrograde rotation: rotate clockwise (westward). They are Venus, Uranus and Pluto. Mercury, Earth, Mars, Jupiter, Saturn and Neptune have direct rotation: rotate anti-clockwise (eastward). All the nine planets revolve around the sun eastward or anti clockwise.
Why is the moon a planet?
It doesn't count as a planet because it revolves around Earth, and therefore is a satillite of Earth, the planet. Satillites revolve around the planets, and the planets revolve around the sun.
What are the effects of the earth's revolution around the sun?
Depends on what you mean by "effects"! By itself, Earth's revolution around the Sun doesn't do much. By comparison, think of the Moon: it revolves around the earth without rotating on its axis, and its relation to the Earth is pretty static. The Earth doesn't rise or set on the Moon, it just hangs there motionless in the sky (more or less, I'm leaving out some minor motions). Such would be the view from earth if all the Earth did was revolve around the sun! The same side would always be in daylight, making it incredibly hot. Consequently, the opposite hemisphere would be incredibly cold, getting no sunlight at all. However, the earth doesn't just revolve around the sun; it rotates on its axis, and its axis is tilted compared to "the plane of the ecliptic", or the imaginary disk that the Sun, Earth, and all other "real" planets revolve in. So, because the earth's axis is tilted and that tilt always points in the same direction as the Earth goes around the Sun, the hemisphere getting the more direct light at one point in the Earth's orbit will get less direct light 180 degrees away in the orbit. In short, the revolution of the Earth around the Sun with the tilt in the earth's axis causes the seasons. Of course, we wouldn't notice those seasons if the Earth didn't also rotate on its axis, giving us day and night. In fact, if it didn't rotate, we couldn't even define its axis! Another effect of the revolution of the Earth is the difference in length between the solar and sidereal day, or the day as measured from noon to noon and the day as measured from when a fixed star rotates back to the same position respectively. Naively, you'd think that these would be the same, but the sidereal day is slightly shorter! I'll let you puzzle this one out for yourself. Imagine the earth going around the sun and at the same time rotating on its axis: what would have to happen to make the sidereal day shorter than the solar day? Longer? Another interesting effect is the fact that the Earth doesn't exactly revolve around the sun but rather a mutual center of gravity that is a weighted average dependent on the relative masses of the two bodies. This center of gravity is off-set from the center of the sun and both the sun and the earth revolve about this. For this reason the sun does a little circle orbit of the same period as the earthly year.
What do all the planets in the Solar System have in common?
Here are a few commonalities.... They are all in direct orbit around the sun. They are all approximately spherical in shape. They were all formed around the same time. They all orbit the sun on a similar plane. They all orbit the sun in the same direction.
What is between inner and outer planets?
The inner planets are Mercury, Venus, Earth and Mars and the outer planets are Jupiter, Saturn, Uranus, and Neptune. I wouldn't count Pluto as a planet cause there thoughts about Pluto could possibly be Neptune moon
How is a moon different to a planet?
Planets are in direct orbit around the sun, while moons are in orbit around the planets.

Direct center of the galaxy?
The direct center of the galaxy varies constantly based on the movement of planets, stars, and celestial objects. The center of most galaxies is based on a large star or planet but may simply be an open space.
Do the inner planets have direct or in direct orbit?
All the planets have direct orbits round the Sun.
What can be thought of as the dividing line between the inner planets and outter planets?
Between the orbit of Mars and Jupiter, there is the asteroid belt. This is made up of millions of small rocks that are in a direct orbit around the sun.
Why are the moons of the gas giants not consideres to be planets?
Because to be planets they have to be in a direct orbit round the Sun.
Has Pluto cleared the neighborhood around its orbit?
Dwarf planets have not cleared their neighbourhood of other object, their neighbourhood being other bodies that are orbiting the sun at the same distance. This is what makes them dwarf planets. If they do clear their neighbourhood (while also being in direct orbit around the sun and being approximately spherical in shape), then they would be calls planets.
Planets moving around stars have been directly observed outside the solar system?
False. No planet has been directly observed. All planets (exoplanets) have been detected using non direct methods or inferred methods.
What are called monor plants?
Minor planets are astronomical objects that areÊneither classified as planets or comets. They are also in direct orbitÊwith the sun.Ê
Where can I purchase a direct TV remote?
You can purchase a direct TV remote at any electronics retailer. I would go to your local shopping center to have a look around and search for the best price for the product you are searching for.
What types of Non-Planetary Objects Inhabit the Solar System?
Besides the 8 recognised planets in our solar system, there are also minor plants and dwarf planets. These still orbit our sun, but are not large enough to qualify as a planet. There are also comets - small bodies of rock and ice that are in a highly eccentric orbit around our sun, asteroids, which are smaller objects in orbit around the sun (mainly between orbits of Mars and Jupiter), Kuiper belt objects, which are out beyond the orbit of Neptune and Oort cloud objects, which is further out still. There are also moons and artificial satellites - not in a direct orbit around the sun, but in direct orbit with objects that are then rhemselves in direct orbit around the sun.
What does the company Power Direct offer?
