Olympus Mons – Highest peak of the Solar System

Olympus Mons – An extinct volcano on the Red Planet, rises almost 22 km! However, the issue of measurement is contentious. So depending on where we measure the vertex. It can grow up to 26 km.

Its diameter is also impressive – at the base it is 624 km.

The volcanic crater itself is about 85 km long, 60 km wide, and up to 3 km deep. However, future Martian climbers will not be particularly delighted. Because Olympus has a gentle, 5-degree slope.

Impressive sizes can also boast:

Rheasilvia, huge impact crater with a diameter of 505 km. Covering up to 90% of the West’s asteroid surface (22.5 km high).
Series of almost even peaks on the Saturn’s moonIapetus, (approx. 20 km). And South Boösaule, the highest hill on Jupiter’s moon – Io (approx. 18 km).

Space probe Voyager 1 – Duration and range record

Space probe Voyager 1 – It’s so far from Earth that it sends out radio signals. They need 20 hours to reach us. This is a record not only in terms of duration, but also coverage. The Voyager 1 probe, launched in 1977, is currently the furthest sent object made by our civilization.

In 2012 passed the so-called heliopause.

The area where the solar wind pressure becomes less than the interstellar wind pressure. Thus leaving the solar system. More importantly, the probe is still working and sending data. Its plutonium battery should ensure operation at least until 2025.

Even then, Voyager 1 will fly ahead.

Although it moves at a huge speed of over 60,000 km / h. If we measure it in relation to the position of the sun. Only for 30 thousand years will pass the Oort cloud – the furthest cluster of matter gravitationally connected to the solar system. He will leave us for good, heading toward the constellation Ophiuchus.

GJ 273b – Exoplanet in the constellation Little Dog

GJ 273b – Planet orbiting the Luyten star

ESI: 0,86
Size: 1,47 Earth
Mass: 3 Earth
Equivalent temperature: -6°C

Twelve light-years from our solar system, Luyten’s star, the red dwarf, wanders from Earth in the constellation Little Dog. Astronomers have discovered two exoplanets next to it. At the same time one of them belongs to the superearth category and at the same time circulates at the edge of the ecosystem. In contrast to the many other planets whose parent star is a red dwarf, GJ273b knows what day is and what is the night. Usually, the planets move close enough that their rotation is connected, and their parent star only puts one hemisphere.

The relatively small weight of this planet indicates that its surface can be flooded by a deep ocean.
According to some speculations, here is 250 times more water than in the Earth’s oceans.
The first measurements showed that the planet is moving outside of the living zone, but now it seems that it will enter it safely. Exoplanet can boast a dense atmosphere and is so close to its star that it circulates in four days. It only drops by 4.3% more light than on Earth. Although TRAPPIST-1d circulates its star in synchronous rotation, a dense atmosphere in which there should be a lot of water vapor helps in thermal exchange. The difference between the illuminated and the dark hemisphere is not like that of other celestial bodies.

TRAPPIST-1e – Exoplanet from system TRAPPIST-1

TRAPPIST-1e – The stony exoplanet of the TRAPPIST-1 system, according to physical properties, is the “e” from the planetary system TRAPPIST is the most similar to Earth.

ESI: 0,85
Size: 0,9 Earth
Mass: 0,8 Earth
Equivalent temperature: -22°C

It moves in the middle of the ecosystem of the entire collection, but there is the least water here. TRAPPIST-1e has a smaller size than Earth, but it has a larger mass. Possible inhabitants would have to be smaller in height and more important to cope with the pressure of local gravity. Red dwarfs, to which the TRAPPIST-1 star belongs, do not emit as much light and heat as the Sun. This means that the ecosphere, in which liquid water can sustain in proper conditions, is located in much closer orbits than in our solar system. A year on the planet TRAPPIST-1e lasts six ordinary earth days.
The planet probably also has a compact atmosphere where hydrogen is lacking. This type of atmosphere can also be found on the rocky planets of our solar system. Hydrogen is also a greenhouse gas, if it was a large amount in the local atmosphere, the surface of the planet would be uninhabitable.

Solar System coldest place – Space probe discovery

Solar System coldest place – American space probe Lunar Reconnaissance Orbiter (LRO), close to the pole of the Moon, on the southwestern edge of the crater Hermite discovered the coldest place of the solar system. The temperature was -249 ° C, thus lacking 24 ° C to the point of absolute zero. Substance cooled to -273.15 ° C, or to absolute zero, has no thermal energy. It is a place which does not escape any direct sunlight.

Solar wind – The Sun has an impact on the processes

Solar wind – The Sun has an impact on the processes in the solar system in many different ways. Although gravity is maintained thanks to its system time emits a space wide range of molecular types of radiation, to which the feature ” wind of the Sun”. Researchers from the University of Leicester have combined the data. Obtained during the observations of solar activity from data obtained during observations of the Martian atmosphere, provided by satellites. The solar corona disappears from the environment until 2.5 x more particles. Observations were conducted during the fall of solar activity within the 11 – year solar cycle.
