The Condensation Theory: This theory
proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the Moon formed in orbit around the Earth
. However, if the Moon formed in the vicinity of the Earth it should have nearly the same composition.
What are the 3 theories of the Moon?
There are three theories as to how our planet's satellite could have been created:
the giant impact hypothesis, the co-formation theory and the capture theory
.
What is the meaning of condensation theory?
The condensation theory of the solar system
explains why the planets are arranged in a circular, flat orbit around the sun, why they all orbit in the same direction around the sun
, and why some planets are made up primarily of rock with relatively thin atmospheres.
What are the 4 theories of the Moon?
Other proposed scenarios include captured body, fission, formed together (condensation theory, Synestia), planetesimal collisions (formed from asteroid-like bodies), and
collision theories
.
What is the theory of the Moon's formation?
What is most widely accepted today is
the giant-impact theory
. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.
Who made condensation theory?
This theory also proposes that the Moon and the Earth condensed individually from the nebula that formed the solar system, with the moon formed in orbit around the Earth. This theory was presented by
Robert Jastrow
.
Who proposed condensation theory?
In 1796 the
French mathematician-astronomer Pierre Simon de Laplace
tried to develop the nebular model in a quantitative way.
Where is Theia now?
A new study led by Qian Yuan, a geodynamics researcher at Arizona State University (ASU), Tempe, suggests that
the remnants of Theia is still inside Earth
, probably located in two continent-size layers of rock beneath West Africa and the Pacific Ocean. Seismologists have been studying these two rock layers for decades.
Is Earth Made of 2 planets?
In other words, Earth is made up of
two fused planets — Earth and Theia
— the study suggests. “Theia was thoroughly mixed into both the Earth and the moon, and evenly dispersed between them,” lead author Edward Young, a professor at the University of California, Los Angeles, said in a statement.
Is Moon a planetesimal?
Planetesimals in the Solar System
A few planetesimals may have been captured as moons, such as Phobos and Deimos (the moons of Mars) and many of the small high-inclination moons of the giant planets. … The most primitive planetesimals visited by spacecraft are the contact binary Arrokoth.
What is the sister theory?
The sister theory—
the Moon formed together with (but independent of) Earth, as we believe many moons of the outer planets formed
. The capture theory—the Moon formed elsewhere in the solar system and was captured by Earth.
What is the temperature range on the Moon?
The average temperature on the Moon (at the equator and mid latitudes) varies from -298 degrees Fahrenheit (-183 degrees Celsius), at night,
to 224 degrees Fahrenheit (106 degrees Celsius) during the day
.
What is the co formation theory?
A co-formation theory proposed
that the Earth and
.
moon formed contemporaneously as a gravitationally bound pair
. The third. theory suggested that the moon formed as an independent planetary body that. was later “captured” by the Earth during a close pass.
What force causes the planets to stay in orbit around the sun?
Gravity
is the force that keeps planets in orbit around the Sun. Gravity alone holds us to Earth's surface. Planets have measurable properties, such as size, mass, density, and composition. A planet's size and mass determines its gravitational pull.
What would happen if the moon fell to Earth?
The Moon's gravitational
pull causes tides on Earth
. Tides that might have been the encouragement for life in our oceans to move on land. … The Moon's plan to destroy Earth by bumping into it would break into pieces the moment it reaches the Roche limit. The Moon itself would shatter, never making it to Earth's surface.
What does the nebular theory explain?
Currently the best theory is the Nebular Theory .
This states that the solar system developed out of an interstellar cloud of dust and gas, called a nebula
. This theory best accounts for the objects we currently find in the Solar System and the distribution of these objects.
