The first planet discovered outside our solar system is named after the Roman goddess of the night sky and stars. The planet, called Cosmo, was found by a team of astronomers using a telescope in Chile.
A newly discovered planet has twice the mass is a topic that is not very common. This planet was found by astronomers, and it is only the second time that this type of planet has been discovered.

A newly discovered planet has been found to have a density 2 times that of the Earth. The new planet, Cosmo, was first spotted by an artificial satellite orbiting it at a fixed distance. Surprisingly, the two stars that were thought to be its only inhabitants are actually quite close together- only 1.2 AU away! This discovery raises many questions about how this strange world came to be and what kind of creatures might live on it.
A newly discovered planet is found to have density, twice the mass of the Earth, but the acceleration due to gravity on the surface of the new planet is only half that on Earth. How can this be possible?
The answer lies in a property of orbits known as centripetal acceleration. Centripetal acceleration is the result of a force that makes an object move in a circle (or another curving path). It’s always pointing toward the center of the circle (or curve), and its magnitude is given by:
ac = v^2/r
where v is the velocity of the object and r is the radius of curvature of its path. In our example, we can think of r as being equal to the radius of the new planet. Since v^2 is proportional to 1/r, we see that ac is proportional to 1/r^2. But since r doubles when you go from Earth to the new planet, 1/r^2 decreases by a factor of 4. That means centripetal acceleration decreases by a factor of 4 as well. And since gravity is a force that produces centripetal acceleration, we conclude that gravity must be only one-fourth as strong on the new planet!
A newly discovered planet is found to have density. This new world has twice the mass of the Earth, but the acceleration due to gravity on its surface is only half that on Earth. Given that both planets have the same radius, what can you conclude about their compositions?
The two artificial satellites, 1 and 2, move in stable circular orbits around a common center of mass. If their orbital radii are r1 and r2 respectively, what is the ratio of their orbital periods?
Two identical stars, each with mass m, are a fixed distance d apart. What is the total mass of the system?
The planet’s characteristics
A newly discovered planet is found to have density. This new world has twice the mass of Earth, but the acceleration due to gravity on the surface is the same as what we experience on our home world. The two artificial satellites, 1 and 2, move in stable circular orbits around this planet. A satellite moves in a stable circular orbit when it has enough speed to balance out the pull of gravity from the body it is orbiting. Two identical stars, a fixed distance d apart, can be seen in the night sky.
The significance of the discovery
The discovery of a new planet is always an exciting event. But this particular discovery is extra special because it has implications for the habitability of other worlds. This newly discovered planet has twice the mass of Earth, but its acceleration due to gravity is only slightly higher than ours. That suggests that it has a much lower density than our planet ufffd meaning that it’s probably made mostly of gas and liquid, rather than solid rock. And that raises the possibility that there could be other planets like this out there in the universe ufffd worlds that might be able to support life as we know it.
The search for life on Cosmo
A newly discovered planet is found to have density:
This new planet has twice the mass of Earth, but the acceleration due to gravity is only slightly higher. However, the day length is much shorter. The climate is also different, with colder temperatures and less sunlight. Despite these differences, life is still possible on this new planet. There are two artificial satellites, 1 and 2, orbiting the planet. Satellite 1 moves in a stable circular orbit at a constant altitude of 500 kilometers. Satellite 2’s orbit is more elliptical, and it varies between 100 kilometers and 1000 kilometers above the surface of the planet. These two satellites are used to search for life on the new planet.

The future of Cosmo
A newly discovered planet is found to have density:
This new planet is much more massive than Earth, but its acceleration is only twice that of our home world. This indicates that the new world must have a very different composition ufffd it must be made of some extremely dense material. This find could help us to better understand the formation and evolution of planets in our universe.
Two artificial satellites, 1 and 2:
Satellite 1 is in a stable orbit around Earth, while satellite 2 is in a similar orbit around the new planet. Both satellites are identical in terms of their mass and composition. However, due to the difference in gravity between the two worlds, satellite 2 will experience a much stronger force from the new planet than satellite 1 experiences from Earth. This will cause satellite 2 to speed up or slow down over time, depending on its position relative to the new world.
The future of Cosmo:
As we continue to explore our solar system and beyond, we may find more planets with strange compositions that can teach us about the formation of planets and how they evolve over time. Who knows ufffd maybe one day we’ll even find another earth-like world out there!
A newly discovered planet has been found to have twice the mass of Earth, but the acceleration due to gravity on the planet is only slightly higher than that on Earth. This means that the planet must have a very low density.
Two artificial satellites, 1 and 2, are in stable circular orbits around a common center of mass. The two satellites have identical masses and are separated by a distance d. If the radius of satellite 1’s orbit is r1, then the radius of satellite 2’s orbit must be:
r2 = r1 + d
