It’s been almost two years since we last saw a planet.
In February, NASA launched the Cassini spacecraft, which will study the outer solar system, to look for evidence of life in the cosmos.
The next month, it took Cassini deep into the asteroid belt to study Saturn’s icy moon Enceladus.
The spacecraft will take another 10 years to reach Mars.
And this September, NASA’s Dawn spacecraft will arrive at the dwarf planet Ceres.
These are the biggest discoveries in planetary science in a decade, and they’ll help scientists understand the early stages of planetary evolution.
We’ve already seen Ceres, but scientists are still not sure what’s up there.
We know it’s made of a complex mix of materials.
But it also has a rocky core and a liquid ocean.
And it looks like it has a large ocean on its surface.
We still don’t know what that ocean is made of, and what kinds of things are up there on it.
And the best thing about these discoveries is that we know we can’t just sit back and hope that something big will pop up.
Ceres is a big part of that.
Dawn will be the first mission to look at the planet since it was discovered in 2008.
It’ll collect data about Ceres’ climate and composition.
It’s the first spacecraft to land on the dwarf.
And as we’ve covered before, scientists believe Ceres may be home to water.
This is an incredibly exciting time for the planet, and it’s also a chance for the human race to get a little closer to it.
Ceres may have a lot of water, but that doesn’t mean it’s the source of the water.
Ceres doesn’t have a water ocean.
The planet’s crust is composed of rock, ice, and sand.
Ceres isn’t made of any of these materials, which means that the planet is also cold.
It has a thick layer of ice that makes up only about one-third of the planet’s surface.
Ceres has about 30 percent of its surface covered in ice, making it much colder than the Earth’s surface at its freezing point.
That means Ceres doesn.t have the ability to hold as much water as Earth.
So it may have lots of water in it, but it doesn’t produce it directly.
Instead, it absorbs and stores water.
Scientists believe Ceres’ water is mostly frozen liquid methane, which makes up about one quarter of Ceres’ mass.
It also has enough hydrogen to make methane and ammonia, which are two important gases that are used to make fuel.
So Ceres’ liquid methane may be the main source of water on the surface.
In fact, Ceres may contain as much as a third of its mass in liquid methane.
It might be a little warmer than the surface of Earth.
Ceres orbits the sun at a distance of about 20 million miles (32 million kilometers).
The orbit around the sun takes it roughly one billion miles (three billion kilometers) from Earth every year.
If Ceres were to become too hot to support life, the planet would be too far away to support any life at all.
The same thing could happen if the planet were too small.
The gravity of the sun and the planet could force the planet to move faster than it should, or even cause the planet itself to explode.
If there is no life on Ceres, it’s possible that it will eventually turn into a dwarf planet.
The dwarf planet can’t hold on to its water.
It can’t survive.
It will probably collapse in on itself if it has too much water.
And, in the meantime, Ceres’ gravity will be too weak to keep Ceres from becoming a planet again.
In the early days of the discovery of Ceres, researchers assumed that Ceres would be a rocky planet.
They believed that the rock layers on the planet are composed mostly of ice and sand, which gives the rock the appearance of a crisscross pattern.
However, researchers have now discovered that the composition of Ceres doesn, in fact, look like a planet at first glance.
The scientists discovered that a very small portion of Ceres is composed mostly or entirely of water.
The water is only about three-quarters of Ceres mass.
In addition to being a little colder than Earth, Ceres is about five times farther from the sun.
Ceres’ atmosphere is made up mostly of hydrogen.
And that hydrogen is much less dense than the atmosphere of Earth or Mars.
It doesn’t get much more dense than water, so it’s actually quite cold, which can cause it to remain a planet for a long time.
The amount of hydrogen that Ceres has, though, is quite high.
In this picture, we can see that Ceres is actually much denser than the water on Earth.
This tells us that Ceres probably doesn’t contain enough water to support a planet in the early Earth, and therefore doesn’t form an ice planet.
Ceres does, however, contain enough hydrogen that it can be a pretty stable planet
