Category: Origin of Asteroids
Asteroids, like other small bodies, are of eruptive origin. These are volcanic ejections from planets and large satellites.
What is the age of comet Hartley-2?
Let’s look at Comet Hartley-2. How old is it? According to modern cosmogony, all comets formed 4.5 billion years ago from the primary matter of a nebula. None of the […]
A small asteroid put scientists at a dead end
Let’s look again at the photos of the asteroid Itokawa and comet Hartley-2, made on the same scale:
Comets and asteroids
According to the conventional view of the origin of the solar system, there is a strong difference between comets and asteroids.
The shape of small asteroids
Here are a few small asteroids, the shape of which is known.
How does the asteroid Ida spin?
So, one of the five asteroids we considered (Matilda) has a spherical shape, the second (Ida) is an ellipsoid, the three remaining (Gaspra, Eros, Itokawa) are dumbbell. They are two […]
Rotation of asteroids
If you throw a dumbbell, a pear or a skittle, be sure to give it a spin. The axis of rotation will have some direction.
The shape of asteroids
Let’s see, what shape small asteroids have. What do they look like? They liik like splinters from a collision or figures of rotation?
Figures of Rotation
In traditional cosmogony, asteroids are fragments of larger asteroids that were formed as a result of collisions. From this point of view, the shape of such fragments can be very […]
Origin of Asteroids
A huge number of small bodies of the Solar system are between the orbits of Mars and Jupiter – this is the so-called Main Belt of asteroids. How did it […]
