How long would it take to get to the dwarf planet Ceres?
Ceres is the largest of the asteroids, in the asteroid belt between Mars and Jupiter. Originally, astronomers thought it was the "missing planet" between Mars and Jupiter, but more observations revealed that there were a great many objects in that region. In 2006, the International Astronomical Union defined a "planet" for the first time, and came up with a definition of "dwarf planet" that included Pluto and Ceres. With conventional rocket engines, it would take about 3 years to reach Ceres. ...

What is the largest asteroid in the Asteroid Belt?
The largest body in the asteroid belt is Ceres, with a diameter of about 950 km. Although it has long been considered to be an asteroid, Ceres was classified as a "dwarf planet" on August 24, 2006. (The other dwarf planets are Pluto, Makemake, Haumea, and Eris.) The issue of whether Ceres remains an asteroid was not addressed at that time. ...
Why did scientists know about Ceres for so long before the other dwarf planets?
The answer to this question can be simplified because Ceres is much nearer than any other dwarf planet in our solar system. Ceres is in the Asteroid Belt which lies between Mars and Jupiter All the other known Dwarf Planets lie in the Kuyper Belt passed and beyond the reaches of Neptune's Orbit of the Sun. Ceres was then (1801) under mathematical scrutiny as to it's very existence and it's orbit was then unknown. Ceres is only 580 miles across but from earth...

Is the length of a day on Ceres the same as how long it takes for it to rotate on its axis?
Yes it is.That's the same for any planet or dwarf planet.A " day" is defined as the period of rotation.There are other definitions, but they are all very similar in most cases....
Asked in Dwarf Planet Ceres
Why was Ceres first a planet?
Ceres was the first asteroid belt object to be discovered, and astronomers of the time had long speculated that a planet might exist between the orbits of Jupiter and Mars. Later, the discovery of other asteroid belt objects cast doubt on Ceres' status as a planet. ...
Asked in Asteroids
How big can an asteroid become?
Ceres, now classified as a dwarf planet, was long regarded as the largest asteroid in the solar system at 588 miles across. It is now ambiguous as to whether Ceres still qualifies as an asteroid. If not, then the largest known asteroid is Vesta with a mean diameter of 326 miles. ...
Asked in Planetary Science, The Solar System
Is there a new planet in your solar system?
No, there are no new planets in our solar system. They have all been here for a long time! Our solar system has eight planets, since Pluto was downgraded to a dwarf planet. There are some new dwarf planets: Eris, Ceres, and the newest MakeMake. There are about a dozen more candidates for dwarf planet status. Pluto, Eris, and MakeMake are also considered plutiods, which means they are beyond Neptune's orbit. See Related Links below for more information. ...
Asked in Planetary Science, Dwarf Planet Pluto
What is the proximity of Pluto to the other planets?
Pluto is no longer a planet. It is considered a dwarf planet or Kuiper Belt Object. The closest planet to it is Neptune and that is a long way off. ...
