what are some similarities between the sun and earth?
601917
The Sun and the Earth both have hotter core, i.e. there surface is much more cooler than that of its core. Sun and Earth both have gravity. Sun and the Earth doesn't change its shape. Both are in the same galaxy, The Milky Way.

Earth is a rotating sphere that orbits the Sun. The Earth's axis of rotation is at a constant tilt with respect to its orbit around the Sun, resulting in the change of seasons. The physical characteristics of the Earth include its size and composition. The Earth also has gravity and magnetic force fields.

Mars and Earth are very different planets when it comes to temperature, size, and atmosphere, but geologic processes on the two planets are surprisingly similar. On Mars, we see volcanoes, canyons, and impact basins much like the ones we see on Earth.

Believe it or not, it actually is just a coincidence — and a happy one at that. The Moon and Sun have virtually the same angular size in our sky because the Sun is about 400 times wider than the Moon, but it's also about 400 times farther away.

Mars and Venus are the two terrestrial planets most similar to Earth. One orbits closer to the Sun, and one orbits more distant to the Sun. But both are visible with the unaided eye, and two of the brightest objects in the night sky.

In absolute terms, the Sun and the Moon couldn't be more different in size. The Sun measures 1.4 million km across, while the Moon is a mere 3,474 km across. In other words, the Sun is roughly 400 times larger than the Moon. ... From our perspective, the Sun and the Moon look almost exactly the same size.

The terrestrial planets are all composed of solid materials such as rock or silicate, contain metals throughout their crusts, and all possess a solid surface. Another similarity is that all travel around the sun in a oval, or elliptic, orbit, and at various eccentricities.

The similarity in size and density between Venus and Earth suggests that they also share a similar internal structure: a core, mantle and crust. The Venusian core is also partially liquid like Earth because the two planets have been cooling at about the same rate.

The Sun is made up of hot clouds of gases, but the Earth and the moon are simply made up of rocks. The moon revolves around the Earth, the Earth revolves around the Sun and the Sun revolves around its own axis. The earth is a planet, the Sun is a star and the moon is a natural satellite.

Earth, Sun and Moon The mass of the sun is 1.99 x 10^30 kilograms, while the Earth weighs in at 6.0 x 10^24 kilograms. The gravitational constant is 6.67 x 10^-11 meter^3 / (kilogram - second^2). So the Earth and sun pull on each other with a force equal to 3.52 x 10^22 newtons.

The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planets (Figure below). They are similar to Earth. All are solid, dense, and rocky.

We tend to lump Uranus and Neptune together in our thoughts, almost as if they're twin worlds. They are nearly the same size – bigger than Earth, but smaller than Jupiter or Saturn – and both are bluish or bluish-green, with deep atmospheres and icy interiors.

Mars and Venus. Mars and Venus are the two terrestrial planets most similar to Earth. One orbits closer to the Sun, and one orbits more distant to the Sun. But both are visible with the unaided eye, and two of the brightest objects in the night sky.

Earth and Venus are approximately the same size, both have an atmosphere, and have a similar topography. Evidence shows that Mars once had a much denser atmosphere, had oceans, and probably had life at one time. And, there's a chance that Mars still has life of some form. These are just a few of the similarities.

Jupiter and the sun are both very similar in their overall composition, as they are both made up almost entirely of hydrogen and helium. The sun has a core that is so hot that it causes hydrogen to separate into individual electrons and protons; Jupiter's core is made of liquid metallic hydrogen.
