Earth and Space

During the next half term we will be learning about ‘’Earth and Space’. Our focus in science will be on the shapes and relative sizes of the Earth, Sun and Moon. We will be using models to explain how the three bodies move relative to each other and how these movements relate to night and day.

As part of this, your homework over Christmas is to find three interesting facts about Earth and Space that you think no one else will know and post these facts here as a comment.

Good luck and Merry Christmas.

  1. . Earth is the third planet from the sun and is the largest of the planets.
    .The Earth was formed4.54 billon years ago.
    .The Earth’s rotation is gradually slowing.
    .Earth has a powerful magnetic field.
    There i only one natural satellite the planet Earth.
    .Of all the planets in our Solar system , the Earth has the greatest destiny .
    .The Moon is the Earth’s only natural satellite.
    .A Solar Eclipse is a natural.
    .The largest moon is the Saturnian system.

  2. Triton, one of Urans’s moons, orbits the opposite way to other moons, Uranus orbits around the sun by rolling and Pluto has a moon amost the same size as it.

  3. It takes eight minutes for the height of the Sun to reach Earth.
    The Moon has no atmosphere and so we can still see the damage caused billions of years ago.
    The Sun has a diameter of 2,715,395 miles (4.730,005 kilometres)

  4. Did you now the length of Mercury’s day is 4222.6 hours.
    Did you now Neptune’s distance from the sun is 4495.1 miles.
    Did you now Venuses rotation period is _5832.5 hours.

  5. The sun is 300,000 times larger than earth
    The solar system was formed 4.6 billion years ago
    Even though Mercury is the closest to the sun it’s not the hottest.

  6. About 50 tonnes of space dust and rocks fall to Earth each day.
    Earth has one moon and its name is Luna.
    The Earths atmosphere extends out to 10,000 km.

  7. Facts about space

    .the mass of mercury is 330,104,000,000,000 billion kg(0.055x Earth)
    .Mars is the fourth planet from the sun and named after the Roman god.
    .neptune is the eighth planet from the sun making the most solar system.

  8. .The Sun/Surface is about 5505 Degrees Celsius

    .The Suns distance from Earth is 149,600,000 KM

    .The core of the Sun is the part that creates the Pressure and Temperature of the planet

  9. .It was a full moon on Christmas eve and it won’t happen again on Christmas eve until 2026.
    .The solar system formed over 4.6 billion years ago.
    .In 2008, 5 dwarf planets were discovered these were called Pluto, Seres, Eris, Makemake and Haumea.

  10. 1.Every year the moon moves 3.8cm away from the Earth – which when you think about it is actually a fairly large
    2.As a result, the Earth spins at 0.002 seconds per day slower every century. That then means that our days are actually getting gradually longer.
    3.A of rock that orbits the Earth and follows an elliptical orbit around the sun along with us. Interestingly there are several asteroids (at least three) that follow this pattern. The first to be discovered was the 5km Cruithne.

  11. .A star is a giant ball of gas.
    .The universe is forever expanding
    .The biggest star could go into the sun more than 3 billion times.

  12. 1.)Most assume that an area as enormous as outer space would have some noise. Surprisingly, outer space is totally silent. This is due to the fact that sound waves require a medium in order to travel from one point to another. Outer space has no atmosphere to permit such travel. Astronauts can talk to one another and Earth-based personnel thanks to the use of radio waves. 2.) When humans venture into outer space, the skin on their feet peels That might sound disgusting, but it is true. In an environment like space with no gravity, astronauts do not need to use their feet to walk. As a result, the skin on the feet becomes soft and peels right off. Unfortunately, astronauts can’t do laundry in space.
    3.)The Earth’s star is the sun. It is immensely dense. The sun is so massive that it takes up 99 percent of the solar system. This is why it has such strong gravity. Scientists have classified our sun as a “G-type main sequence star”. This classification means that the sun fuses around 600,000,000 tons of hydrogen to helium every second.

  13. 1. The earth is not a perfect sphere, due to its rotation it is slightly distorted in shape.

    2. The only planet that spins backwards compared to the other planets is Venus.

    3. How many people have landed on the moon? Between 1969 and 1972 twelve people have landed on the moon. The next trip is planned for 2020.

  14. – Venus is the hottest planet in the solar system with a temperature of around 450 degrees.
    – Saturn isn’t the only ringed planet, other gas giants such as Jupiter, Uranus and Neptune also have rings, they are just less obvious.
    – Jupiter’s four biggest moons are named Europa, Ganymede, Callisto and Io.

  15. .The moon (or Luna) is the earths only natural satellite and was formed 4.6 billion years ago around some 30-50 million years after the formation of the solar system.
    .The sun is the star at the centre of the solar system and is by far the most important source of energy for life on Earth.
    .The sun is roughly middle aged and has not changed dramatically for four billion years, and will remain fairly stable for another four billion years.

  16. 1. All The Stars Are Planets
    2. All Planets Move Round The Sun At Different Speed
    3. So Far Only Earth Is Liveable By Humans

  17. -99.86% of the Solar System’s mass is found in the Sun
    – The hottest planet isn’t closest to the sun.
    -The edge of the Solar System is 1,000 times farther away than Pluto.

  18. Uranus and Neptune are gas giants like Jupiter and Saturn.
    Smaller stars live much longer than huge stars.
    Young stars often stay together in clusters.

  19. 1: The furthest away mankind has been away from our planet is the Moon ,
    2: Space Has no atmosphere and is a vacuum
    3: The universe it’s self is only 13.7billion years old
    4: we measure distant of light in light years because the universe it’s self is to large to be measured in meters,kilometres …..
