Our solar system was formed about four and a half billion years ago, from a massive cloud of gas and dust which collapsed on itself, producing the Sun and later its surrounding planets VIDEOGRAPHIC

00:00About four and a half billion years ago, a large cloud of gas and dust collapsed on itself,
00:13and due to the force of its own rotation, flattened into the shape of a disc.
00:18At the center, where the mass is the most concentrated, the matter is subjected to immense pressure.
00:23Hydrogen atoms are crushed against each other, fusing together in nuclear reactions.
00:28This is the birth of the Sun. These nuclear reactions continue today.
00:33Around it, the dust collides and coalesces into larger and larger pieces, known as planetissimals,
00:39the building blocks for planet formation.
00:41When these bodies are large enough, gravity shapes them into spheres,
00:45and they absorb smaller objects in their path.
00:48Those which have cleared their orbit by eliminating the other bodies of similar size, earn the status of planets.
00:54Near the Sun, where it's hotter, heavy materials like silicon and iron clump together more easily.
01:01Planets which form there are small, dense, and have a solid surface.
01:05Planets further away form a mantle of lighter elements like hydrogen.
01:09They are very large, but not very dense. These are the gas planets.
01:13The remaining materials, which never formed a planet, continue to travel around the Sun, like comets and asteroids.
01:23It's by studying the distribution and composition of these small, unused blocks of matter,
01:29which allows us today to retrace the stages in the formation of the planets.
01:43So this is really weird that this Does Epidemic subset into the planets.
01:48This can be used to journaling form a planet that's rooted in the dimensions of near the past.
01:51So that's a way of writing here.
01:53I'm sure there are no signs in it.
01:55I'm skipping to the planet from the transactions ofastoise in the connaissance and Corinthians too,
01:58that's actually a kind of location for XOE
02:02Or something like that and it's in the spotlight.
02:05Other names may that titles have just come to mind.
02:07So that's the mystery of
