Mercury was heavily bombarded by comets and asteroids during and shortly following its formation 4.6 billion years ago, as well as during a possibly separate subsequent episode called the Late Heavy Bombardment that ended 3.8 billion years ago. [56] Mercury received impacts over its entire surface during this period of intense crater formation ...
Caravaggio is an example of a Peak ring impact basin on Mercury. Several areas on Mercury are extremely dark, such as a small crater within Hemingway crater in the lower right. The geology of Mercury is the scientific study of the surface, crust, and interior of the planet Mercury. It emphasizes the composition, structure, history, and physical ...
Mercury, being the closest to the Sun, with a weak magnetic field and the smallest mass of the recognized terrestrial planets, has a very tenuous and highly variable atmosphere (surface-bound exosphere) containing hydrogen, helium, oxygen, sodium, calcium, potassium and water vapor, with a combined pressure level of about 10 −14 bar (1 nPa).

It was discovered by MESSENGER during its second flyby of Mercury on October 6, 2008. [1] The crater is 3.9 billion years old, and was created during the period of Late Heavy Bombardment. [1] The density and size distribution of impact craters along Rembrandt's rim indicate that it is one of the youngest impact basins on Mercury. [3]
Like Earth's, Mercury's magnetic field is tilted, [9] [23] meaning that the magnetic poles are not located in the same area as the geographic poles. As a result of the north-south asymmetry in Mercury's internal magnetic field, the geometry of magnetic field lines is different in Mercury's north and south polar regions. [24]
On January 28, 2025, Mercury enters Aquarius—the planet of mental, cerebral matters, communication, and learning transits detached, objective Aquarius energy.The collective seeks a bird's eye ...
[3] [1] The name Hokusai was suggested by radar astronomer John K. Harmon. [4] The crater has a diameter of about 100 km; the rays extend for thousands kilometers, covering much of the northern hemisphere. [5] Hokusai is the fourth-largest crater of the Kuiperian system on Mercury. The largest is Bartók crater. [6]
