Assuming it's a sphere, the volume of the asteriod is 4pi/3 x (100,000)3 cubic meters. Let's assume it's half rock and half ice (by volume). The mass of rock is then 2pi/3 x (100,000)3 cubic meters times ... well, it depends on the KIND of rock, but 2.5 tonnes per cubic meter is a fairly representative value for lots of kinds of rock. The mass of ice is the same volume figure, but the density of ice is about 0.9 tonnes per cubic meter.
The specific heat of rock again depends on the type of rock, but just as a rough estimate let's say 200 calories per kilogram kelvin, which is kind of in the middle of the range. The specific heat of ice is actually dependent on the temperature, but as a rough average over the range in question let's call it 400 calories per kilogram kelvin.
So for the rock that's roughly 2 x 1015 cubic meters x 2.5 tonnes/cubic meter x 200 kcal/tonne kelvin, which comes out to a bit more than 1018 kcal per kelvin, and since we're heating it by 250 kelvin, let's call it 2.6x1023 calories. Multiply by 4.184 to get joules and it's about 1.1x1024J for the rock.
The ice part is a little trickier because there's a phase transition in there. I come up with about 7x1023J to get it to 273K. Heating the liquid water from 273K to 293K will bring the total up to about 9x1023J. However, melting that much ice will take about 6x1023J. All in all, it turns out the water part takes about 1.5x1024J total.
All told (and keeping more significant figures than I can really justify), we're looking at about 2.6x1024 J. There's a LOT of room for variation in there, depending on what kind of rock it is exactly and what the relative proportions of ice and rock are, but somewhere in the low single digit yottajoules is the right ballpark.

What is the energy of an asteroid?
The energy of an asteroid can be determined by its kinetic energy, which is proportional to its mass and velocity squared. The potential energy of an asteroid in a gravitational field is influenced by its distance from a massive body. When an asteroid collides with a planet or another space object, the energy released can be significant and potentially catastrophic.
How big was the asteroid that hit russia?
The Meteorite that impacted russia on 15th feb 2013 was15-metres in diameter and weighed around 7,000 tonnes. Hitting the atmosphere at 18 kilometres per second it blasted out windows and caused light structural damage.
Does an asteroid completing an orbit around the sun conserve energy?
Yes, everything obey the conservation of energy laws.
Why is energy not a compound mixture or element chemistry?
Energy is a property not a matter.
Is energy a mixture?
No, energy is not a mixture. Energy is a property of matter and systems that can be transferred or converted but does not have a physical composition like a mixture does. Mixtures consist of two or more substances combined, whereas energy manifests in various forms, such as kinetic, potential, thermal, and chemical, but does not exist as a tangible substance.
How big was the k-t asteroid?
The impacting bolide that formed the crater was at least 10 km (6 mi) in diameter and delivered an estimated energy equivalent of 100 teratons of TNT(4.2×1023 J).4/3 pi r3 = 520 km3
What is the energy of an asteroid?
The energy of an asteroid can be determined by its kinetic energy, which is proportional to its mass and velocity squared. The potential energy of an asteroid in a gravitational field is influenced by its distance from a massive body. When an asteroid collides with a planet or another space object, the energy released can be significant and potentially catastrophic.
Is energy an compound or mixture?
No, energy is NOT an element, a compound or a mixture.
An asteroid that is moving farther away from the sun is gaining what type of energy?
While getting farther from the Sun in its orbit, an asteroid (or other object) will gain potential energy, and lose kinetic energy.
Is energy an element mixture or compound?
No, energy is NOT an element, a compound or a mixture.
Is energy a mixture or a compound?
As energy has no mass, it is not a matter. Hence, it is neither a compound or a mixture.

The Meteorite that impacted russia on 15th feb 2013 was15-metres in diameter and weighed around 7,000 tonnes. Hitting the atmosphere at 18 kilometres per second it blasted out windows and caused light structural damage.
Which asteroid, out of the two asteroids approaching the Earth at the same speed, possesses a greater amount of kinetic energy?
The asteroid with the greater mass will possess a greater amount of kinetic energy when approaching Earth at the same speed.
Is a monster energy drink an element compound or mixture?
Red bull is a mixture. The only drink that is not a mixture is water.
Does an asteroid completing an orbit around the sun conserve energy?
Yes, everything obey the conservation of energy laws.
Can an asteroid hit a moon?
yes but that would add energy to the moon's orbit
Does an asteroid belt have a source of energy?
Asteroid belts do not have a source of energy in the same way that planets or stars do. However, asteroids in the belt can gain energy from sunlight, which can cause them to rotate or move within the belt. Additionally, collisions between asteroids can also release energy.
