do asteroids have a core?

Generally, no. The structure of asteroids and planets is actually quite different. While planets have a clearly defined internal structure, ranging from molten metal cores to rocky or gas based exteriors, asteroids have a much simpler one.

Smaller asteroids are much more common. All asteroids orbit the Sun in the same direction as the planets. The vast majority of asteroids that have been catalogued are located in the asteroid belt between the orbits of Mars and Jupiter; however, not all asteroids are located in the asteroid belt.

The innermost layers of the Earth. The Earth has an outer core (liquid) and an inner core (solid). They are not chemically distinct from each other, but they are chemically distinct from the mantle. The core is mainly composed of nickel and iron.

Asteroids certainly hit the sun after having their orbits disturbed by the planets - most objects with unstable orbits only have a few possible destinations in the solar system (the Sun or the planets).

The C-type or carbonaceous asteroids are grayish in color and are the most common, including more than 75 percent of known asteroids. They probably consist of clay and stony silicate rocks, and inhabit the main belt's outer regions.

One of his arguments is that the IAU's wording is vague, and that—like Pluto—Earth, Mars, Jupiter and Neptune have not cleared their orbital neighbourhoods either. Earth co-orbits with 10,000 near-Earth asteroids (NEAs), and Jupiter has 100,000 trojans in its orbital path.

1 Answer. Inner planets have solid rocky cores, outer planets are mostly gas. Similar in that they are all part of our solar system.

The outer core is 2,300 kilometers (1,429 miles) thick, while the inner core is 1,200 kilometers (746 miles) thick. The outer core is mainly composed of a nickel-iron alloy (liquid iron), while the inner core is almost entirely composed of a pure solid iron body.

Space debris smaller than an asteroid are called meteoroids. A meteoroid is a piece of interplanetary matter that is smaller than an asteroid and frequently are only millimeters in size. Most meteoroids that enter the Earth's atmosphere are so small that they vaporize completely and never reach the planet's surface.

The earth's inner core is a solid ball of iron, nickel and other metals, while the outer core is liquid metal composed of iron and nickel as well. ... The outer core is believed to be about 2,300 kilometers (1,400 miles) thick, and is located 2,890 kilometers (1,400 miles) beneath the surface of the Earth.

The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).

They are characterized by having orbits lying always within the region of the outer planets. The sizes of those discovered so far is comparable to the larger asteroids and hence they are much bigger than a typical cometary nucleus.

Asteroids are smaller than a planet, but they are larger than the pebble-size objects we call meteoroids. ... An asteroid is a small rocky object that orbits the Sun. A meteor is what happens when a small piece of an asteroid or comet, called a meteoroid, burns up upon entering Earth's atmosphere.

Every day, countless objects that came from comets and asteroids fall to Earth. What happens when they hit the atmosphere depends on their size and composition. Most of these particles are the size of dust grains. They simply float down to the surface.

Asteroids are rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, ranging in size from hundreds of miles to several feet across. In total, the mass of all the asteroids is less than that of Earth's moon.
