Which of the following is thought to explain many of the “exceptions to the rules” of our solar system? …
There are clear patterns to the rotation and orbits of large bodies in the solar system. There are vast numbers of asteroids and comets
. There are a few notable exceptions to the rules.
How can we explain the exceptions to the rule in our solar system?
Most of the exceptions
probably arose from collisions or close encounters with leftover planetesimals
, especially during the heavy bombardment that occurred early in the solar system’s history. Our Moon is probably the result of a giant impact between a Mars-size planetesimal and the young Earth.
Are there any exceptions to the rule that planets rotate with small axis tilts and in the same direction that they orbit the sun?
Are there any exceptions to the rule that planets rotate with small axis tilts and in the same direction that they orbit the Sun?
Venus, Uranus, and Pluto are exceptions
.
What is the best explanation for how the solar nebula was cleared of debris?
The solar nebula was cleared of
gas through the pressure of the sunlight (called radiation pressure) and through the massive solar wind
. The nebula was cleared of some of the leftover debris by the Heavy Bombardment period.
What are the two exceptions to the rules that we find in our solar system?
Describe at least two “exceptions to the rules” that we find in our solar system? Answer:
Uranus rotates nearly on it’s side and Venus rotates backwards
. Also, while the terrestrial planets have no moons or very small moons, ours is the largest Moon in the solar system.
What are the four major features of our Solar System?
- smaller size and mass.
- higher density (rocks and metal)
- solid surface.
- few moons and rings.
- closer to the Sun.
What are some of the examples of exceptions to the patterns of our Solar System?
Exceptions to the rules: The generally orderly solar system also has some notable exceptions. For example, among the inner planets only earth has a large moon, and
Uranus is tipped on it’s side
. A successful theory must make allowances for exceptions even as it explains the general rules.
What is the only planet with rings?
Saturn
is a funny-looking planet. True, it’s not the only planet with rings. Jupiter, Uranus and Neptune have rings, too. But Saturn’s rings are the biggest and brightest.
Which is the most metal rich terrestrial planet?
Mercury
is the largest celestial body of this type in the Solar System (as the other terrestrial planets are silicate planets), but larger iron-rich exoplanets may exist. Iron is the sixth most abundant element in the universe by mass after hydrogen, helium, oxygen, carbon, and neon.
Which planet rotates anti clockwise?
The
planet Venus
. Contrary to many people’s beliefs, not all the planets on the solar system rotate around the sun in an anti-clockwise pathway. It is however interesting to know that there is an exception.
What are the 6 stages of nebular theory?
- Nebula, protosun forming, spinning planetary disk, protoplanets forming,
- Shock waves from a nearby supernova explosion.
- It also begins to flatten.
- Protosun.
- When the gravitational forces begin to fuse hydrogen into helium (fusion)
- Protoplanets.
- Inner protoplanets – most of their lightweight gases are boiled away,
How was the solar system formed?
The Sun and the planets formed together, 4.6 billion years ago,
from a cloud of gas and dust called the solar nebula
. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. … After the Sun ignited, a strong solar wind cleared the system of gas and dust.
Is our solar system in a nebula?
Discover how a giant
interstellar cloud
known as the solar nebula gave birth to our solar system and everything in it. The solar system as we know it began life as a vast, swirling cloud of gas and dust, twisting through the universe without direction or form.
What are Jovian planets?
Also called “giant planets,” the Jovian planets
occupy orbits in the outer solar system at distances ranging from 5 (Jupiter) to 30 (Neptune) times the Earth’s
distance from the Sun. … The planets also have fierce winds and storms, and a rapid rotation. When compared to Earth, the Jovian planets are enormous.
What are the four inner planets called?
The planets Mercury, Venus, Earth, and Mars, are called
terrestrial
because they have a compact, rocky surface like Earth’s terra firma. The terrestrial planets are the four innermost planets in the solar system.
What kind of object is Pluto explain quizlet?
Explain. Pluto is
a dwarf planet
. It is essentially a large comet, in the Kuiper Belt. It is mostly ice and rock.
