1 Ceres (seer'-eez (key), IPA , ) was the first asteroid to be discovered (indicated by the '1' in its name).
1 Ceres
1 Ceres is by far the largest of the asteroids, comprising more than a third of the total mass of the main asteroid belt. Ceres is also the smallest of the dwarf planets. orbit: 446,000,000 km from the Sun (average) diameter: 950 km ...
Ceres completes a rotation within 9.1 hours. Based on its relatively round shape, density, and rotation rate, astronomers believe that Ceres may have a layered (or "differentiated") interior like those of of the rocky inner planets such as Earth.
Ceres: A Dwarf Planet
Can You Believe it?
Since its discovery in 1801, Ceres has been considered a comet, a planet, an asteroid, and a dwarf planet.
Ceres: the original Pluto
We are typically biased by the history we have personally experienced. For most people living today, Pluto's story and status has been emblazoned in our minds since our school days.
Asteroid Ceres
For two centuries it was the largest known rock in the solar system. The Texas-sized asteroid Ceres, about 930 kilometers (580 miles) across, was the first asteroid ever detected.
Ceres
For many years Ceres was thought to be the biggest asteroid in the Solar System. It is about 600 miles wide and contains about 25% of the mass of all the asteroids combined.
Ceres , Minor planet names 1 Ceres, is the smallest identified dwarf planet in the Solar System and the only one in the asteroid belt.

One kind of asteroid, called Apollo asteroids, cross the orbit of the earth as they move around the sun.
Ceres has been known since 1801 and is the largest of the asteroids. It was the first asteroid ever discovered. Its mass is more than one-third of all the 3,000 recorded asteroids. Ceres is about 578 miles in diameter.
CERES

Ceres,[e] Pallas, Juno, and Vesta
The first known asteroids, from their discoveries between 1801 and 1807 until their reclassification as asteroids during the 1850s.[41]
Ceres has subsequently been classified as a dwarf planet.
Ceres is the only asteroid large enough for its gravity to force it into a roughly round shape, and so, according to the IAU's 2006 resolution on the definition of planet, is now considered a dwarf planet. Its orbital distance, 2.
1 Ceres is the largest of all the objects in the asteroid belt and is classified as a dwarf planet.
Asteroid 1 Ceres, with a diameter of about 930 kilometres (km), is the largest, followed by 2 Pallas at 535 km and 4 Vesta at 520 km. The fourth largest asteroid, 10 Hygiea, has a diameter of about 410 km.
Largest asteroid 1 Ceres Total discovered to date Over 250,000 designations have been assigned by the Minor Planet Center; over 100,000 have been observed more than once. Total numbered asteroids to date.
He named this light Ceres, after the pagan goddess of Sicily (!!!) and after finding a few more, he correctly labelled these objects, planetoids.
Permanent designations consist of numbers and names, beginning with (1) Ceres, given to asteroids for which orbits are accurately determined. Names are generally proposed by the discoverer.
Instead, they honor the astronomer Nicolaus Venator, who was assistant to the famed astronomer Giuseppe Piazzi, the latter the discoverer (in 1801) of the first-known (and largest) asteroid, Ceres.

The first asteroid to be discovered wasn't found until 1801 and was named Ceres. This is also the largest of the asteroids, about 940 km wide.

Ceres gave order to Triptolemus to teach humanity in how to grow grain. King Karnabon showed friendly hospitality when Triptolemus came to him, but after a short while he changed his attitude completely and tried to kill Triptolemus.
The largest asteroid is Ceres, about 900 kilometers in diameter. [C95]

The masses of Mercury and Venus (as well as those of our own Moon and the asteroid Ceres) are a little harder to determine accurately because these bodies have no natural satellites of their own.
In late September 2007, NASA launched the DAWN spacecraft to explore the two largest asteroids, Ceres (about 960 km in diameter) and Vesta (520 km in diameter), for about six months at each asteroid.
It was classified as a Dwarf Planet in 2006, along with Ceres, which is the largest main-belt asteroid. Pluto is a Kuiper Belt Object, composed of material left over after the formation of the other planets (see Comets in the next section).
He named it "Ceres" after the Roman goddess of grain. Ceres is the largest known asteroid at approximately 950 km (590 miles) in diameter, ...
The largest representatives are Ceres, with a diameter of about 930 km (about 578 mi); Pallas, with a diameter of about 552 km (about 343 mi); and Vesta, with a diameter of about 521 km (about 324 mi).

According to the IAU decision, the solar system will now have a total of 8 planets and 3 'dwarf planets': Pluto, Ceres and the unnamed 2003 UB313.
Some asteroids, such as 1 Ceres, 2 Pallas, and 4 Vesta, are nearly spherical and probably should be termed protoplanets or planetesimals.
If the asteroids Ceres and Vesta, for example, could be observed at the same distance, Vesta would be the brighter of the two by roughly 10 percent.
The largest of these asteroids is Ceres, which because of its size is considered a dwarf planet.
NASA's Dawn spacecraft will arrive at Vesta in 2011, and Ceres in 2015. They are the two largest asteroids in the Solar System; indeed, Ceres is classed as a dwarf planet and is 950 kilometres wide.
To the Greeks she was either the goddess Demeter or her daughter Persephone (Roman: Ceres or Proserpina).
The largest, Ceres, has a diameter of about 933 km, most are much smaller. Over one hundred thousand have had their orbits described, but only a few of the larger ones are bright enough to be picked up in binoculars.
The largest known asteroid is Ceres, located in the asteroid belt. Ceres is 950 km in diameter and much larger than the other asteroid belt objects, which are typically < 100 km in diameter.
It is interesting to note that, historically, the first four asteroids (1 Ceres, 2 Pallas, 3 Juno and 4 Vesta) were considered planets for several decades (their size was not accurately known at the time).
They range in size from Ceres, with a diameter of about 1000 km, down to a few centimeters or less. The ajacent image shows the asteroid Gaspra, as photographed by the Galileo space probe (Ref).
In Roman times the goddess Ceres was depicted: the goddess of the growth of food plants and harvests, and particularly corn. Her festival was in the second week of April, the same time that the constellation appears in the Spring skies.
Asteroids and dwarf planets, such as Ceres, also may offer a look back to the early solar system. Closer to home, humanity is again looking to its own moon both as a crucial source of historical information.

Asteroids have been fascinating scientists for hundreds of years. The first asteroid to be discovered was Ceres, in 1801. Since then literally tens of thousands of asteroids have been observed flying willy-nilly across our solar System.

1801, 1 January Giuseppe Piazzi discovers Ceres, the first known asteroid.
Giuseppe Piazzi (1746-1826) was an Italian astronomer who discovered and named the first (and largest) asteroid, Ceres, on January 1, 1801. Asteroids are large, rocky objects that orbit the Sun in a belt between Mars and Jupiter.
...
Many of these objects orbit the Sun between Mars and Jupiter. Their sizes range anywhere from 33 feet (10 meters) in diameter to less than 620 miles (1,000 kilometers). The largest known asteroid, Ceres, has a diameter of 579 miles (926 kilometers).
Virgo's connection to fertility was recognized as well by ancient Egyptians (Isis), Assyrians (Astarte) and Greeks (Ceres). In other Greek myths, Virgo corresponds to Astrea, godess of justice, holding the Scales (Libra).
The closest dwarf planet to the Sun is Ceres, which lies within the asteroid belt, then there is Pluto, which normally lies just beyond Neptune, and finally there is Eris, discovered in 2005, which normally lies beyond Pluto.

According to Hyginus, some people also saw it as the island of Sicily, which was originally known as Trinacria on account of its three promontories. Trinacria was the home of Ceres, goddess of agriculture.
