CMEs are massive bursts of solar plasma and magnetic fields that erupt from the Sun’s corona and travel through space. As they move outward, their internal structure changes, which affects how they interact with planets and influence space weather. This study focuses on how a particular CME, observed on Nov 4-5, 2021, evolved as it traveled through a short radial distance of 0.14AU. The event was seen by two spacecraft: Solar Orbiter at 0.84 AU and Wind at 0.98 AU. By analyzing plasma and magnetic field data from both, we measured how fast the CME expanded and calculated an expansion parameter that shows the CME was expanding faster than usual, a behavior known as “super-expansion.” We also looked at pressure changes and found that, although magnetic pressure dropped as expected, the thermal pressure increased sharply, which is unusual. This suggests that the plasma inside the CME was still being heated and its momentum was being redistributed. The rates at which density and pressure decreased with distance were different from what standard models predict, pointing to more complex processes like uneven expansion or local compression. Our findings emphasize the value of multi-point measurements for understanding CME evolution and space weather forecasting.
