What is the mass of the largest asteroid?
(The total mass the asteroid belt is lighter than the moon. The total mass the asteroid belt is lighter than the moon.) However; If the total mass of the asteroid belt were reconstituted, it would altogether be less than half of the mass of the moon. But if we consider that if the hot molten interior of a hypothesized planet that might have been the asteroid belt was under great pressure and heat, as are all of the known planets, we could then hypothesize that approximately 90+% of the mass of said hypothesized planet would have been expanded by a factor of at least 1600:1. Possibly more if the interior was superheated. That figure is only if the matter of the interior had the matter weight and density of water. If it were denser, having the same density of magma, then the rate of expansion would be much greater. Possibly as much as 12000:1. So if you take this into consideration, then the asteroid belt could indeed have had a total mass great enough to compete with one of the terrestrial planets
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 would be much larger visually from a reasonable telescope than say Pluto or any other of the Dwarf planets in the Kuyper Belt. Ceres is the first ever asteroid to be discovered
How old is the asteroid Ceres?
Ceres is pretty much the same age as most other objects in the solar system: about 4.6 billion years.
Is an asteroid bigger than Pluto?
No. Pluto is bigger than Ceres. With a diameter of about 2302km, Pluto is quite a lot bigger than Ceres. Ceres has a diameter of about 975km.
How much would a 95-kg astronaut weigh on Ceres?
The gravity on Ceres - which is a "dwarf planet" or "plutoid" in what is called the asteroid belt - is 3% of Earth's. If the weight of an average man on Earth is 175 pounds, then on Ceres he would weigh 2.25 pounds.
How much percentage would the mass be if Ceres would suddenly leave the asteroid belt?
The mass would not change!
Is Ida the biggest object in the asteroid belt?
No. The largest object in the asteroid belt is Ceres. Ida is much smaller.
Is there a planet in the asteroid belt?
There is a "dwarf planet", Ceres, the largest object in the Asteroid Belt, and a great number of smaller rocks. (Prior to its reclassification, Ceres was referred to as the largest asteroid.)

Why do scientists refer to it as an asteroid belt and not a planet?
Currently the combined mass of all the asteroids in the asteroid belt is much less than that of any planet, though there were probably many more asteroids in the belt when the solar system was young. One of the leading hypotheses is that gravitational disturbances from Jupiter prevented a planet from forming where the asteroid belt is.
How much gravity does the asteroid belt have compared to earth?
The asteroid belt is not a single object. You would have to assess the gravity on each asteroid individually.
How old is the asteroid Ceres?
Ceres is pretty much the same age as most other objects in the solar system: about 4.6 billion years.

Why didn't the asteroid belt make a planet?
There are multiple theories for the material in the asteroid belt. First, note that the entire mass of the asteroid belt objects is a few percent of Earth's mass -- what is there today would not form much of a planet. One fairly good theory is that a planet did have an irregular orbit with the highest part where the asteroid belt is today. However, the planet's highly elliptical orbit brought it across the orbits of Mars and Earth. It collided with Earth, leaving much of its mass in the Earth but also spewing out material that eventually formed our Moon. A small portion of the material survives in the asteroid belt and as the small moons of Mars.
Is Uranus inside or outside the asteroid belt?
The asteroid belt is located between the orbits of Mars and Jupiter. As such, the outer planets (or Jovian planets) can be said to be outside the asteroid belt. That is, they are located beyond the belt and are therefore further away from the sun than the belt.
