At breakfast, enjoy the glittering world with the stars

In the early morning, early risers will witness a multitude of stars and a brilliant star.
At that time, saturn, bright Mars, Venus with a lute, the moon, and a dazzling heart will appear in the sky at the same time.
The moon will cast its light on The Second Heart. Heart Sudo looks very similar to Mars, so it is also called "Fire". It is located in the core area of Scorpio. It is well known among amateur astronomers because it is a red giant star and is at the end of its life.
To the southwest before sunrise, the reader can go out in search of the stars, especially the three bright "worlds" described above. Three stars are visible to the naked eye, but if the reader has binoculars or telescopes, they can be seen more clearly.
Before sunrise, Venus is easily seen in the southwest direction, and at the same time, it shines with a white glow of -4.7 brightness. Below Venus is the red planet of Mars, which is closer to longitude 1 due to the end of the month. (In contrast, most people with normal vision can see a dim star of 6 in the dark sky.)

Using binoculars or astronomical telescopes, it will be difficult to observe the details of Mars and Venus. But if you're lucky, you might see Saturn and its rings. Saturn is about 0.7 bright, which is relatively dim, but you can still see it with naked eyes in the sky from east to southeast.
Planetary beads are relatively common because the Moon, Earth, and other planets in the solar system orbit above the same level, what we call the "ecliptic." So even if you miss this opportunity, you can still witness the great triangle of celestial bodies formed by Venus, Mars and Saturn before sunrise on Sunday and Monday (March 27 and March 28).

Saturn is the sixth-farth furthest planet from the Sun and the largest planet in the Solar System after Jupiter. It is a gas giant with an average radius of 9.5 times that of Earth. Its average density is 1/8 of that of Earth, but, due to its enormous size, its mass is more than 95 times that of Earth.
Saturn 's nucleus is more likely to be made of ferronicel alloys as well as rocks ( siloxanes ) . This core is surrounded by metallic hydrogen, with a layer of liquid hydrogen and liquid helium on the outside, and a layer similar to a gas on the outermost layer. Saturn's color appears to be pale yellow because its uppermost atmosphere contains ammonia crystals. It is believed that the currents in the metal hydrogen layer create Saturn's magnetic field. Although Saturn's magnetic field is weaker than Earth's, its magnetic moment is 580 times that of Earth due to its higher mass. Saturn's magnetic force is about 1/20 of That of Jupiter. As for the outer atmosphere, there is nothing worth mentioning. Saturn has wind speeds of up to 1800 km/h, higher than Jupiter but below Neptune.
Mars is the 4th farth farthest planet from the Sun and the smallest planet outside of Mercury. In English, Mars represents the god of war, also known as the Red Planet. The reason why Mars is so red is because the surface of Mars is rich in iron oxides. As an Earth-like planet, Mars has a thin atmosphere and volcanic craters, valleys, dunes, and polar ice caps on its surface.
Mars' diurnal and seasonal changes are similar to Earth's because its rotational period and rotation axis and ecliptic angle are similar to Earth's. Mount Olympus is on Mars, the largest and highest known volcano in the solar system. Mariner Valley is also on Mars, one of the largest canyons in the solar system. The smooth Arctic basin, which covers 40% of Mars' surface area, may have a significant impact on Mars' character. Mars has two moons, Phobos and Phobos, both of which are relatively small and irregularly shaped.
