1. The sun tends to make up the biggest chunk.
two.Some scientists recommend “they might have formed since the young Earth had a thick blanket of hydrogen, which reacted with oxides in the Earth’s mantle to form lakes and seas.” To read the post, click on the Connected Hyperlink.

An report in Wikipedia says that “a lot of scientists think that comets bombarding the young Earth (about 4 billion years ago) brought the vast quantities of water that now fill the Earth’s oceans.”

three.Theheliocentric theory is an argue that men and women feel the sun is in the middle of the universe.

four.Heraclides (330 B.C.) developed the 1st Solar System model, starting of the geocentric versus heliocentric debate.

5.Nicholas Copernicus.

six.______Hydrogen fusing into helium is the main supply of power getting radiated from the sun (a nuclear reaction).

7.The Photosphere

eight. The solar wind is a stream of energized, charged particles, primarily electrons and protons, flowing outward from the Sun, via the solar program at speeds as higher as 900 km/s and at a temperature of 1 million degrees (Celsius).

9.They have a rocky surface, little mass and little or no moons..

10.Mars had water.

11.Pluto (although it really is technically no longer deemed a planet), Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn and Jupiter.(thts from smallest to biggest)

12.They are created up of numerous tiny, separate particles of rock and ice that circle the planet

13. About Earth is the identical

14.Oxygen, water, and gravity

15.Europa is 1 of Jupiter’s Galilean moons, found by Galileo Galilei utilizing a primitive telescope in 1610. These four moons, Io, Europa, Ganymede, and Callisto, are by far Jupiter’s largest all-natural satellites. Europa is the smallest of the Galilean moons. At 3000 km in diameter, it is a bit smaller than the Earth’s Moon. Europa is named for a mistress of the god Zeus in Greek mythology. Jupiter, the planet Europa orbits, was named following the Roman name for Zeus.

16.THe theorogical theory maybe not confident

17.it wasn’t killed, it was just not known as a planet anymore due to how tiny it is. Its essentially a metoer or a star

18.Sunspots are dark spots that migrate across the surface of the sun. They can be as massive as 60,000 miles across, and are triggered when magnetic fields under the surface of the sun are twisted and poke via the sun’s photosphere.

19.biggest star

20.The typical distance from the Moon to the Earth is 384,401 kilometers (238,857 mi). The moon has a slightly elliptical orbit, about 356,000 kilometers (221,600 miles) distant at perigee and 406,997 kilometers (252,950 miles) at apogee.

21. Each and every four.25 years
