asteroidal
- adjective
- /ˌæstərˈɔɪdəl/
- At these times especially, asteroidal particles may be gently delivered to our upper atmosphere, giving us free (although small!) samples of the asteroid belt!
- asteroidal impact
- asteroidal dust
- asteroidal particles
Examples
-
This "bottleneck" in the flow of dust toward the Sun results in a ring of asteroidal dust grains associated with the orbit of the Earth.

Their detailed calculations show that dust particles originating in the asteroid belt are trapped in resonant orbits with the Earth and that our planet is embedded in a ring of asteroidal dust surrounding the Sun.
Academic text (1994) -
The result is that there is a cloud of asteroidal particles that constantly travels behind the Earth!

But cometary or asteroidal impacts may warm the surface sufficiently to melt water ice.
Academic text (2000) -
One fundamental difficulty is that we do not know exactly where the majority of meteorite specimens come from within the asteroidal main belt.

Hence, the spectral properties of asteroids become different from those of their associated meteorites, making the identification of the asteroidal parent body more difficult.

The NASA workshop considered the hazard of both asteroidal and cometary impacts and made recommendations for programs to enhance the discovery rate of both classes of objects.
Academic text (1992) -
When we add together the contributions of all the particles in all the different resonant orbits, we find that there is an enhanced ring of asteroidal particles traveling around the Sun with the Earth!
Academic text (1994) -
In particular, asteroidal surfaces are known to be altered by a process called "space weathering," which is probably caused by micrometeorite and solar wind action that progressively transforms the spectra of asteroidal surfaces.

Scientists plan to study the asteroidal characteristics of the newly discovered space object.

Etymology
Asteroidal comes from asteroid, where aster means 'star' and the ending -oid means 'like' or 'shape'. So asteroidal describes something 'relating to' or 'like' an asteroid, for example a small, rocky body or a surface that looks like one in space.
