I did a moon sized asteroid, this is what it says
''The Earth is completely disrupted by the impact and its debris forms a new asteroid belt orbiting the sun between Venus and Mars.
100 percent of the Earth is melted
Depending on the direction and location the collision, the impact may make a very small change in the tilt of Earth's axis (< half a degree).
Depending on the direction and location of impact, the collision may cause a change in the length of the day of up to 123 hours.
The impact does not shift the Earth's orbit noticeably.
The average interval between impacts of this size is longer than the Earth's age.
Such impacts could only occur during the accumulation of the Earth, between 4.5 and 4 billion years ago.''
