The density of an asteroid differs.

The best way to determine an asteroid's density involves more than just comparing its reflectivity; it typically requires a combination of techniques. Radar mapping can provide information about an asteroid's size and shape, while spectroscopic imaging helps identify its composition. To calculate density, scientists often use mass estimates derived from gravitational interactions or spacecraft measurements combined with volume estimates from radar or imaging data. Thus, a comprehensive approach is most effective for accurately determining an asteroid's density.
determining its mass from its gravitational pull on a spacecraft, satellite, or planet.
Yes, even the smallest asteroids can create massive craters because they are travelling at such tremendous speeds. Several variables can affect the size of the crater, including the size, speed and density of the asteroid, the density of the ground and the angle at which the asteroid strikes.
This is not really a realistic scenario; an astronomer would first figure out the mass and volume, and THEN calculate the density based on these pieces of information.Anyway, first you would get the volume, as density / mass. Then, from the volume, you can calculate the radius, using the formula of a sphere. This will only work for fairly large asteroids; for smaller ones it would be a very rough approximation - small asteroids usually have irregular shapes.
That will depend on the exact shape, and the material it is made of.You can get an estimate, by assuming a spherical shape, calculating the volume, and multiplying that by some density (for example, the density of water). The actual mass may be a bit more than that if its a rocky asteroid; a bit less if it's ice, for instance.
The impact of asteroid Apophis, which is about 340 meters in diameter, would create a crater up to 5-6 kilometers in diameter if it were to hit Earth. The exact size would depend on various factors such as the asteroid's density, speed, and angle of impact.
That's right; Ceres is the largest asteroid.

The asteroid missed the Earth's atmosphere by inches.We will begin asteroid mining soon.
The odds of successfully navigating an asteroid field depend on various factors, such as the density of the field, the size of the asteroids, and the skills of the pilot. In general, navigating an asteroid field is extremely challenging and dangerous due to the potential for collisions with the asteroids. It's often considered risky and should be avoided whenever possible.
If there is an atmosphere, the light will gradually dim as the asteroid approaches the asteroid.
